The Best Utility Knife

If you’re looking for a utility knife for general around-the-house use, we recommend the Milwaukee Fastback II ($15). After 26 hours of research and hands-on testing of 21 different knives, we found that, simply put, this knife has it all. It can be easily (and quickly) opened and closed with one hand. It has a comfortable grip with all the right contours and finger notches. Changing blades is easy and it has a nice, springy belt hook. For increased safety, the knife locks in both the open and closed position. And finally, despite its thin profile, it still has room to store one additional blade.

If you’re heading down the path of an aggressive DIY lifestyle and feel that the ability to store multiple blades on a knife is essential, we recommend that you go with the Olympia Turbopro ($16). Even with its extremely compact body (thinner than the Fastback II), it still has the capability to house five additional blades. It also has an auto-load feature to make blade changes freakishly easy. It’s a nice durable knife and the butt end has a small carabiner clip so it can be hooked on a belt loop.

For those of you who aren’t comfortable handling a utility knife and will only use it for really basic tasks, we recommend the Milwaukee Self-Retracting Knife ($12). This knife has a spring-loaded blade that withdraws into the handle as soon as the thumb slide is released. While this feature makes it a very safe knife to use, it also limits the ways you can hold it, making it difficult for anything more than very basic cutting.

Why a utility knife?

…ideal for all of the grunt-work cutting that’s too difficult for scissors and too dulling and damaging for a nice pocket knife.
A utility knife is a fantastic tool to have in the home tool box or junk drawer. It cuts with a removable razor blade, so the edge is both incredibly sharp and very disposable, making it ideal for all of the grunt-work cutting that’s too difficult for scissors and too dulling and damaging for a nice pocket knife. It’s good for jobs like breaking down cardboard boxes for recycling, cutting carpeting, or slicing the painted seam on a stuck window. Other tasks can include sizing a small patch for a linoleum floor, trimming a rug pad, or even opening a toy trapped in a blister-pack nightmare.

The more DIY your lifestyle, the more useful a utility knife can be. Building paper, sheet plastic, drywall, tarps, rope, and even roofing shingles can all be cut with utility knives.

Why you should trust me

I have an extensive knowledge of utility knives garnered from a ten-year career in construction. Most of that time was spent as a carpenter, foreman, and job supervisor at Thoughtforms, a high-end custom builder in the Boston area where I worked on houses like this one. For the past 12 years I’ve carried a utility knife daily, preferring it over traditional bladed knives because of the disposable blades (no sharpening needed). In that time, I’ve probably gone through about 20 different knives, most of which were discarded due to poor features, bad ergonomics, or sub-par durability.

I’ve also been writing about and reviewing tools for seven years, with articles appearing in This Old House, Popular Mechanics, and Tools of the Trade, as well as at my own site,

How we picked

There are a lot of utility knives in the world and only a few credible group tests. This piece in Truckin Magazine and Cop Tool’s Utility Knife Showdown were the most comprehensive and thorough. So to narrow the field down to a single knife, I read what I could and relied on my own experience as well as a number of conversations that I had with Marc Lyman, editor of HomeFixated, a website devoted to tools and home improvement. In addition to being a very credible and honest tool expert and reviewer, Lyman is also a self-confessed knife snob.

utility_knivesBecause utility knives are equipped with razor blades, it makes sense to pay a little extra for a nice one with a full compliment of safety features. Safety Daily Advisor, a newsletter of Business and Legal Reports, reported that up to one-third of all manual tool injuries are attributed to utility knives like box cutters. Over the years, I’ve nicked my knuckles and fingers enough times to have full confidence in that statistic.

So basically, you want a knife that is both safe and easy to use. For that, we recommend a tool that has a very sturdy grip (because you don’t want this thing coming out of your hands); locks both in and out of the tool (so it is less likely to accidentally deploy); can be opened and closed with one hand (for speed and convenience); changes blades quickly and easily (keeping your hands away from the edge of the blade); and has a functional belt clip (for fast storage).

A pro contractor is also going to need a spot for multiple blades, though that’s less of an issue for around-the-house use. But still, room for a single extra blade is certainly an added bonus.

For general tasks, we recommend the folding style for its increased safety, portability, and belt hook.
The largest decision to make is which body type to go with: folding or retractable. For general tasks, we recommend the folding style for its increased safety, portability, and belt hook. We talk more about this in the “Body type” section.

To see what knives are out there, I checked all of the major retailers and tool manufacturers, finally settling on 15 finalists. These were knives that were either highly regarded in individual reviews or were representative of a certain style of blade change or folding mechanism. Others were chosen based on my own positive experiences with them. I also looked at five retractable models, each with unique features, to see what they had to offer.

In selecting models, I stayed away from anything less than $10 or so. My experience is that those cheaper tools are simply marred by poor manufacturing. As Lyman said, “given how frequently a utility knife gets used, I think getting a quality knife is a no-brainer. $20 or less probably isn’t going to break the tool budget either.” The cheap ones, like this $3.99 Stanley aren’t going to cost much, but they offer nothing more than the most rudimentary functionality and safety features.

How we tested

Once I had all the candidates in hand, I put identical blades in all of them and proceeded to break down and slice up about 50 cardboard boxes. I also used the tools to cut out some old caulking and dice up a sheet of drywall.

Because the blades are disposable, sharpness wasn’t a criteria, so I was looking at overall ergonomics, ease of blade change, leverage on tougher cuts, and ease of folding mechanism. For the drywall cuts, I really sunk the blade in the material and tried to work it around to check if the blade would disengage from the knife.

I also carried each one around for a couple days and used them for all of the small knife tasks that I encounter in a 48-hour period. I generally use a knife somewhere between eight and 10 times each day for everything from sharpening pencils to trimming an unraveling thread on a shirt to opening a box of cat litter.

Our pick

The Fastback II can be quickly closed and opened with one hand, has a comfy grip, and makes changing blades crazy simple.
After all my research and testing, the Milwaukee Fastback II ($15) stands at the front of the pack. Lyman agreed, stating that he is a “huge fan” of the knife: “It’s not the cheapest utility blade out there, but it is the best in my opinion.”

The knife is designed so that it can be opened and closed very quickly with one hand and lock in either position. The grip, particularly the large forefinger notch, ensures that the knife won’t slip out of your hands, and the tool has a nice, easy blade change and a flexible belt hook. The Fastback II also has an added gut hook, so you can cut string or open a bag of bird seed without ever unfolding the knife and exposing the blade. The handle also has room to store an additional blade. None of the other knives had such a complete set of features.

Unlike other folding utility knives, this one can be opened and closed with a flick of the wrist once a safety release button is pressed with the thumb. As Lyman put it, the Fastback is “the fastest blade you’ll deploy short of using a switchblade.” But it’s not so much the speed that’s important here as it is the one-handed ease of use. It’s just much simpler than working the thumb slide on a retractable knife or trying to work a normal folding blade open with your thumb or both hands.

In his review of the Fastback II, Clint DeBoer of Pro Tool Reviews wrote, “the knife opens easily with just one hand. And I do mean easily.”

…the blade end of the Fastback locks in both the open and closed positions, so there is less of a chance of the blade’s accidentally becoming exposed.
The blade end of the Fastback locks in both the open and closed positions, so there is less of a chance of the blade’s accidentally becoming exposed. Lyman said, “[the Fastback II] is super easy to deploy and stow, but when stowed isn’t likely to accidentally deploy. It’s just ridiculously user-friendly.”

The handle is another high point of the tool. The Fastback II has a very deep finger groove that allows for an extremely secure grip. This is useful when you have to bear down on the knife, like if you’re cutting a thick cardboard box or scoring a piece of sheetrock to patch a hole in the wall. Just by lightly pinching the tool with your thumb and forefinger with your forefinger in the groove, you make it nearly impossible to pull the knife out of the hand.

But the finger notch is only one portion of the handle’s overall goodness. The back of the grip area contours exactly to the hand and the top edge of the tool is flat, giving the thumb a solid face to sit against during cuts, particularly tougher ones. None of the other knives had grips that were even close to the comfort of the hand-hugging Fastback II.

To change blades, the Fastback II has a simple spring-loaded, push-button release. When it is pressed, the blade pulls out, and when a new blade is put in, the button releases and locks it in place. This procedure can be easily done with your hands coming at the tool from above the blade, increasing the safety level. Remember, these are razor blades, so even a light brush against the edge can do some significant damage. Pro Tool Reviews’ DeBoer said that the Fastback’s blade change, “beats the lever mechanisms on most Gerber, Bessey, and Irwin Quick-Change knives.”

The Fastback II has a wire belt hook as opposed to a solid metal clip. This holds tightly, but at the same time, the wire has a lot of spring which leaves room for some give so you don’t have to force it down over a belt. This, combined with the pronounced bend at the leading edge of the hook, means that it’s almost effortless to clip onto a belt or the rim of a pocket.

The Fastback II also offers a storage area for one additional blade (two, if you really pack them in there). Along the inside edge of the blade pocket is a plastic clip that swings out to reveal a storage spot. The blade inside is held in place by a magnet. It’s the only part of the tool that isn’t metal. It’s also the only thing that separates this tool from the original Fastback, which has no onboard storage.

There are also a few additional features on the Fastback II. Along the underside of the blade holder is a small cut-away designed for stripping wires. To use it, just hold a wire in the notch with your thumb and spin it. The exposed portion of the blade will cut the insulation off the wire. Milwaukee is a pro brand geared toward plumbers, HVAC guys, and electricians, so this feature is cool for them, but it’s sort of a “whatever” feature for the homeowner unless you’re planning on working on your electrical system (in which case it’s a nice added bonus).

A more useful feature for the casual user is the “gut hook,” which lets you cut string and other thin objects without opening the blade.
A more useful feature for the casual user is the “gut hook,” which lets you cut string and other thin objects without opening the blade. This is a deep cut-away at the back of the handle that exposes a small portion of the blade when the knife is in the closed position (don’t worry, it’s nearly impossible to cut yourself on it). This lets you cut a length of twine or open a bag of cat kibble while keeping the blade safely tucked into the tool

Basically, the Fastback II is the only knife that combines the fast, one-handed operation of the retractable knives with the safety of the flip style. Added to that is a host of other features—the massive finger hook, the overall ergonomics, the gut hook, blade storage, and the easy blade change—that make this the tool to beat.

Everything that is good about the Fastback II holds true for the original, just subtract the part about the blade storage.
If blade storage isn’t important to you and you want to save a couple bucks, we recommend the original Milwaukee Fastback ($10). It has the same features as the Fastback II, just no blade storage. The positive side of this is that without the plastic blade clip, the knife is one-eighth of an inch thinner and is made entirely of metal so there’s little chance of breaking any part of it. Just know that it’s a trip to the toolbox every time you dull a blade.

Who else likes them?

The Fastback and Fastback II have garnered a number of very positive reviews from credible sources. Reviewing the original Fastback (remember, they’re the same tool other than the blade storage), Rob Robillard of A Concord Carpenter wrote, “If you carry a folding utility knife, I highly recommend the Milwaukee Fastback flip knife. Once you’ve tried this knife you’ll know what I mean by ‘it feels like quality.’”

Timothy Dahl of Charles & Hudson, also reviewing the original model, “absolutely love[d] this knife. The look and feel is great and the design is unique.”

Lyman’s HomeFixated review of the original Fastback said that it, “is our new favorite accessory. In fact, I use this thing constantly around the house and the shop. It’s utility knife meets pocket knife meets butterfly knife.” He added, “It’s solid, heavy and extremely ergonomic. It’s also very quick to open.” Three years later, he also reviewed the Fastback II and said that by adding the blade storage, “Milwaukee took something great, and made it greater.”

Jay Amstutz, writing at Cop Tool, compared the Fastback to seven popular retractable knives1 and concluded that the best knife “and the blade we will continue to use most often is the Milwaukee Fastback. The clip allows it to easily slide into the pocket; its slim profile is barely noticeable when wearing and we really like the flip action for quickly opening and closing of the blade.”

Jeff Williams, writing about the Fastback II at Tool Box Buzz, said, “I think this knife is perfect now that it has blade storage. Seriously, it’s that good.” He also noticed the ergonomics: “The curve of the back fits perfectly in the palm and the index finger cutout gives great control.” When discussing what can be improved about the knife, he said, “nothing.”

Amazon feedback is also very positive. As of this writing, the tool carries a rating of a perfect five stars with 16 reviews. At, it has a perfect five stars with nine reviews.

The Irwin isn't as refined as the Fastback II and has a trickier opening mechanism, but it has room for two extra blades and can still be closed with one hand.
If you can’t get your hands on the Fastback II, The Irwin FK150 Folding Utility Knife ($13) offers much of the same, but with a trickier opening mechanism and room for two extra blades. While its forefinger notch, one-handed close, and comfortable—albeit smaller—handle helped the FK150 best most of the competition, none of those features were as refined as in the Fastback II.

While the Fastback II is easily opened with one hand, it really takes two hands to open the FK150. It technically can be done with one hand, but it’s difficult and takes a good amount of finger strength. The hinge is very tight, which makes it hard to gain any leverage on the folding portion. The knife would definitely benefit from some sort of thumb stud to make this process easier. But other than that, it’s hard to complain.

The FK150 is almost an inch shorter than the Fastback II, but if you have smaller hands, don’t think that’s going to make it the better tool. My wife tested out both knives and far preferred the larger Fastback because of the way it fit into the curves of her hand.

The FK150 has an additional safety feature that keeps the blade from being removed unless the folding portion is oriented 45 degrees to the handle. Otherwise the blade is completely locked in the tool and it won’t come out, even accidentally.

Irwin also sells an FK250 ($16) which is the step up from the FK150. This knife has both blade storage and a small flip-out screwdriver at the butt end. The blade storage compartment also has a little place to hold an additional bit. Even with all of this going on, the tool maintains a small footprint. If you think the little screwdriver is something that you would use, for a few extra dollars, it’s an option.

If you’re working with tougher materials like roofing shingles, the Turbopro stores more blades than our pick and has an auto-load mechanism for easy blade changes.
If you’re looking to get a little more ambitious with your DIY life, you may want a knife with some serious blade storage. The more aggressive the task, the shorter the life of the blade. Materials like roofing shingles, cement board, and fiberglass insulation can quickly destroy an edge. For this, we recommend the Olympia Turbopro ($16) which seems to be the same as this Seber knife ($15). If I were going to get back into professional construction tomorrow, this is the knife that I would want in my tool belt. The size, blade storage, auto-load, and all-metal construction make it a fantastic pick.

Once I decided that the main pick would be a folding knife, I stopped digging into retractables, but still, with all of my construction experience, I’ve never seen anything quite like this one. Despite its comfortably compact size (the entire thing is almost smaller than the folded-up Fastback), the Turbopro has the ability to store five additional blades.

The knife also utilizes an auto-load mechanism, which makes changing blades seriously easy (and safe).
The knife also utilizes an auto-load mechanism, which makes changing blades seriously easy (and safe). A small side-mounted release allows you to remove the damaged blade out the front of the tool. Then, to load a new one, just move the thumb side all the way back into the tool and a fresh blade shifts into the cartridge from the storage compartment.

Rounding out the Turbopro are a comfortable handle and a small carabiner clip at the rear of the tool.

An extremely safe knife, just not as useful as the others

The blade on this knife retracts automatically when you're not holding it open. It's safer but not practical for more serious jobs.
If you really don’t like the idea of a razor knife and will only be doing light work, the Milwaukee Self-Retracting Knife ($12) is a good option. This retractable knife has a spring-loaded blade tensioned so that it always wants to retract back into the tool.2 To make a cut, you need to press the thumb slide to the open position and hold it there. As soon as you let go, the blade vanishes. It’s certainly a safe system, but it isn’t practical for any involved projects like cutting out the old caulking at the kitchen sink or jobs that need the blade extended for long periods of time like cutting a rug pad.

When the blade is initially loaded into the tool, you can choose between two slots to dictate how much of the blade is exposed when the thumb slide is pushed forward. If you’re only going to use the knife to break down the recycling, you can set it so that only half an inch is showing, rather than three quarters of an inch.

To open the body of the tool and get at the blade storage, the Milwaukee Self-Retracting Knife has a little screw that you can easily operate by hand. Many knives, like the Great Neck, Stanley, and Sheffield require a screwdriver for this task. The knife also has a wire-stripper, like the Fastbacks, and even as basic as the tool is, Milwaukee has put some thought into the ergonomics of the handle.

 The competition

The Irwin FK100 ($12) is very similar to the FK150 except that it doesn’t have any on-board blade storage. It’s much like the relationship between the Fastback and Fastback II: In all other regards the knives are identical. The FK100 is a nice tool, but doesn’t match up to the Fastback, the same way the FK150 doesn’t match the Fastback II.

In addition to the Turbopro, I also tested out two folding knives from Olympia. The 33-200 Turbofold ($11) and the 33-057 Turbofold ($14) are nearly identical except for the fact that the 33-200 has an aluminum shell and the 33-057 has a stainless steel construction. Of the two, I preferred the 33-057 for its heavier weight and nicer overall look.

The good is that the Turbofolds had the easiest blade change mechanism of all the knives. The not-so-good is that they lock in the open and closed position, so two hands are required to fold and unfold the blade. The handles are also not as grabby as the Fastbacks’ and the Irwins’.

The Gerber Superknife SK Edge ($10) looks and acts like a traditional pocket knife. I liked that it took one hand to both open and close, but the handle is on the small side with very little grab to it. There’s nothing too exciting about this knife, but there’s also not a whole lot that detracts from it either. Because of its low-key presentation and light-duty feel, it could be a nice option for an EDC knife.3

It’s worth noting that there are a number of Amazon reviews that describe the blade releasing from the tool during use.
It’s worth noting that there are a number of Amazon reviews that describe the blade releasing from the tool during use. Similar comments appear with this Stanley knife, which is nearly identical to the Superknife (down to the patent numbers on the blade change mechanism, so they likely have the same manufacturer). I took a pair of pliers and tried to work the blade free by moving it back and forth and up and down, but could not get it to release.

The Gerber E. A. B. Lite Pocket Knife ($13) is so small that when it’s folded up it can sit on a credit card with plenty of room to spare. But with this small size come poor ergonomics. With any medium-duty or aggressive cutting, the metal edges started to dig into my hands. Also, the blade changes out with a flathead screw, so it’s not something that can be done quickly or easily. The screw is extremely tiny and could be lost on a rug if it accidentally gets dropped; it took me ten minutes to find after my cat knocked it off the counter.

DeWalt’s Folding Retractable Knife ($20) is an interesting knife in that it is both folding and retractable. To operate it you need to first flip the body open, then a traditional thumb slide exposes the blade. When it’s unfolded, it’s as big as the Fastback with a nice, large gripping area, which gave me good control over the cuts that I made. There’s no question that it’s a solidly built tool, but when compared to the speed of the Fastback’s blade deployment, the extra step of the thumb slide seems unnecessary. Also the comfort of the handle is nowhere near that of the Fastback.

Greenlee’s Heavy-Duty Folding Utility Knife ($18) is a large knife that can store five additional blades. The storage area makes for a sizable grip that is comfortable in the hands. Unfortunately there is no belt hook and this knife is too big for any standard pocket, so storage is an issue. Because of the very stiff hinge and locking mechanism, the Greenlee has a two-handed open and close.

The REVO Folding Utility Knife ($10) was the most interesting design that we looked at. The hinge on this one is a large circular cutout about an inch in diameter. When using the tool, you can hook your finger through the hole and really lock in your grip. It’s effective, but unfortunately the odd handle makes it difficult to hold the tool in any other way. There are plenty of instances, like when cutting out the caulking on a tub surround, when you’re going to be constantly shifting the tool around in your hands and the central bulge on this one makes that difficult.

The Bessey BKWH ($17) is an attractive knife. The handle has wood accents and the tool presents itself as being very well-made. It has the lockback style of fold, which requires two hands to close the knife, so it’s not as efficient as some of the others. But on top of that, it also has the fussiest blade change. To lock in a new blade you have to press against a piece, basically pushing your thumb up towards the underside of the blade while the top piece is being pressed downwards. If it slips…

The Wiss WKF1 ($11) has a fairly grippy handle and is not really a bad knife in any way. It just doesn’t have any features that stand out against the rest.

The Sheffield Lock-Back ($9) is very much like the Bessey, enough so that I suspect that they both came from the same manufacturer (Sheffield also sells this knife, which looks to be identical to the Bessey that we tested). So like the Bessey, the Sheffield was hindered by the blade change and two-handed close.

The knife comparison in Truckin Magazine put a Sheffield knife, very similar to this one, in the top spot. Based on the trouble I had with the blade change, they must not have felt that was an important criteria. I really don’t think it’s a good idea to have your thumb so close to the blade and actually pressing towards it. Even with all of my experience with utility knives (or maybe because of it), I could hardly bring myself to perform this operation.

The Kobalt ($9) is a good example of what I was getting at earlier about inexpensive knives. It works okay, but none of the features have any smoothness to them. It’s a lockback knife, so it takes two hands to close, but in addition, the “fit and finish” of the tool isn’t that great when compared with most of the others. The hinge feels grainy, the fold is stiff, and the blade needs an extra wiggle to lock in. It’s all unfortunate because this was actually one of the more comfortable knives to hold.

The rest

There are quite a few knives that we didn’t test. We discounted models with the two-part blade change found on the Bessey and Sheffield. This Craftsman is a good example of that (it’s also a good example of how many tool companies co-brand the same tool–it looks identical to the Sheffield and Bessey).

Others, like this Snap-On ($19) and the Stanley FatMax ($10) were missing belt hooks. With the quality of knives available with belt hooks, there’s no reason to not have that option for storage.

Gerber’s Transit ($14), much like their E. A. B., uses a screw to change the blade.

Other knives, like this Seber ($29), were priced out of range. There are enough great options under $20 that unless you’re a knife aficionado there’s really no point in spending more than that.

So really, all of the other knives we came across in our research either were missing a feature or just simply didn’t match up to the Fastback II for speed.

Other styles (non-folding)

We tested out a few other styles of knives to see what they offered. They were all retractables and we chose them based on the representative nature of their design. Because I knew from the start that a folding knife was more appropriate for general use, I didn’t delve into retractables too deeply, but based on my own experience (I’ve used many, many retractables over the years), these ones are all worth knowing about.

Top row (Olympia Turbopro, Alltrade Squeeze Utility knife), Middle row (Milwaukee Self-Retracting, Milwaukee Slide Open Utility Knife), Bottom (Olfa XH-1)

Top row (Olympia Turbopro, Alltrade Squeeze Utility knife),
Middle row (Milwaukee Self-Retracting, Milwaukee Side Open Utility Knife), Bottom (Olfa XH-1)

Of the knives, the Milwaukee Side Open Utility Knife ($13) is the closest to the basic construction-level utility knife. But there are a few features that set it apart from other retractables. The thumb slide is on the side of the knife rather than the top, so it’s unlikely that you’re going to accidentally move it while making a cut. Also, when the blade is retracted, the thumb slide is recessed into the side of the knife, making it less likely to deploy while in a pocket. The Milwaukee Side Open has plenty of room for extra blades in a fold-out compartment. This is a nice knife, but the Fastback offers a better grip, a faster blade, and a belt hook.

Other than the Olympia Turbopro, another, much larger auto-loading knife is the Alltrade Squeeze Utility Knife ($12). Despite its large size and massive ten-blade storage compartment, it is very comfortable to hold. A squeeze of the handle exposes the blade and a small toggle button retracts it. Once a dull blade is removed out the front, a fresh blade appears the next time the handle is squeezed.

Because of the number of stored blades and the comfortable rubber padding on the grip area, this is going to be a winner for someone who literally has a knife in their hands all day long.

The Olfa XH-1 ($17) uses a segmented snap blade. These are long blades that can be extended almost their full length if need be (in this case, just over four inches), giving them the ability to cut thicker items like foam insulation. When the edge dulls, take a pair of pliers and break off the end segment to expose a new edge. This eliminates the need for a blade storage area.

The main drawback is that an additional tool is needed to break off the blade segments. Also, to extend a blade you have to deal with a little wheel lock that isn’t exactly fast. For these reasons, it’s not the first choice for around-the-house use, but still, if you feel that you would want to be able to extend a longer blade, the Olfa XH-1 is definitely the most comfortable snap knife that I’ve held. Milwaukee recently released a line as well that also looks to place some emphasis on ergonomics.

What makes a good utility knife

Body type

To get the full range of use out of the knife and as much safety and portability as possible, we recommend going with the folding style over the retractable. They’re smaller to store, tend to come with belt hooks, and because of the way the folded blade nests in the body, there is a lower chance of their accidentally deploying in your pocket. Retractable knives are nice, but their feature set is more geared toward the professional tradesman.

Folding knives are more compact than retractables. The traditional retractable knife is about seven inches long, so they’re a little much for the pants pocket and don’t come with belt clips. But because a folding knife is hinged at the center, when they’re in storage-mode, they’re only about three to five inches long; when unfolded, they offer a similar handle length to the retractables.

The folding knives also generally come with belt hooks, which are a nice feature to have if you’re cutting bags of mulch out in the garden or if you’re using the knife up on a ladder to cut out and re-do some caulking around a window. Even breaking down cardboard boxes it can be helpful. It’s much easier to grab a tool off your belt than it is to have to dig into your pocket.

The best knives are ones that can be folded and unfolded with one hand.
There is a wide range of folding and locking mechanisms. The best knives are ones that can be folded and unfolded with one hand. Chances are you’re already holding on to what you want to cut before you even pick up the knife, so the one-handed operation makes things more efficient. I’ve found that a one-handed close is even more important, seeing as at that point, it’s extremely likely you’ll already have something in your other hand. Think of a task as mundane as sharpening a pencil. A folding knife with a two-handed open or close means putting the pencil down or shifting it back and forth between hands while you work the knife. With a one-handed open and close, the process is far easier.

Retractable knives are longer and more tubular in shape, like a submarine. The blade moves in and out of the tool via a thumb slide, usually situated along the top edge just above the nose. Retractable knives tend to offer a bigger handle, which is better for all-day use, as well as more significant blade storage (five extra blades is typical). Both of these characteristics make them ideal for professionals but are unnecessary for an around-the-house tool.

Because the slide needs to be pressed in order to move the blade, there is a level of safety involved, but it’s usually not a particularly strong locking mechanism. On too many occasions, I’ve had a blade work itself open while in my pocket, probably through some pattern of bending down or climbing a ladder. As Lyman put it, “I’ve never been a fan of carrying something in my pocket that could easily accidentally deploy.”

Another safety concern is that it’s possible to put a retractable in your pocket with a little bit of the blade peeking out.
Another safety concern is that it’s possible to put a retractable in your pocket with a little bit of the blade peeking out. I’ve gotten a number of sharp pokes over the years from this happening. These kinds of things really can’t happen with folding knives. They’re either open or closed and there’s no mistaking which one it is.

Also, the slide mechanism itself can cause problems. According to Lyman, “I’ve never used a retractable with a mechanism that doesn’t eventually get really crud-filled and clunky. I definitely favor folding.” My experience echoes this. It seems that no matter how high the quality, over time the blade slide becomes gunked up,

Some retractable knives, like this Snap-on, have a safety switch that needs to be flipped before putting the knife in your pocket, but why bother dealing with a two-step process when the double-locking folding style guarantees that there won’t be any in-pocket mishaps just by closing the knife?

Also, as I mentioned, Jay Amstutz at Cop Tool did an eight-knife showdown and chose the one true folding knife (Fastback) as the winner over a group of leading retractables.


No matter what you’re doing, from opening a bag of ice melt to cutting an asphalt roof shingle, you want to make sure that you have a good grip on this dangerous tool. Some knives do this with a textured area and others with curved handles or finger ridges at the grip. The best ones are the knives with some kind of finger groove because it’s an actual physical impediment to slippage and has less to do with hand strength. This isn’t to say that you want a light grip, but with your fingers even slightly “hooked” into the tool, it’s far less likely that they’ll slide off.

Blade change

Not surprisingly, there is also some variety in the blade change mechanisms from tool to tool. The best ones are those that are simple and keep your hands away from the underside of the blade.

Many knives use a push-button design. A small spring-loaded button or lever on the knife is pressed to push a locking piece out of the way so a new blade can slide in. When the blade is installed, the button is released and the locking mechanism engages with the blade, holding it in place. Not all buttons are created equal though. I’ve had problems with them gumming up on cheaper knives, but I’ve yet to see any failure from the ones on knives built by respected manufacturers.

Other knives have a two-part system, or a variation on it, where a top piece is pressure-fit over a side piece that holds the blade in place. The tested Bessey and Sheffield have this. It requires you to press up on the side piece while you press down on the top piece. This action puts your thumb very close to the blade edge, actually pressing in its direction.

With so many moving parts, there is more opportunity for a piece to get gummed up over time. I tested two knives with this system (Bessey and Sheffield) because I was curious if the mechanism had been improved upon over the past few years. It hasn’t.

Blade storage

On-board blade storage is a must in a construction or industrial setting where blades are as disposable as tissues, but for around-the-house usage, it’s less of an issue. Lyman explained, “my garage/shop really isn’t that far away. It is nice to have a blade or two on board, but it’s not super vital.” Keep in mind that because of the way the blades fit in a utility knife, you actually get two uses out of each one. Once the blade is worn down, it can be flipped and reinstalled and you can use the other side.

Even with my daily usage of my utility knife, there aren’t too many situations in which I need more than one additional blade at a time.
Even with my daily usage of my utility knife, there aren’t too many situations in which I need more than one additional blade at a time. In construction, there were times when I’d chew through three or four blades in a sitting, depending on the project. If it doesn’t have too much of an impact on the knife’s size, it’s worth it to go with additional blade storage.

The large retractable knives can usually hold up to five extra blades, but most of the flip style don’t have any additional storage, and if they do, it’s usually for only one or two blades, like the Milwaukee Fastback II or the Irwin. But the trade-off here is a slightly fatter handle. Because multiple blade storage isn’t a crucial feature for around-the-house use, you can go for a thinner knife, one that will fit a little better in the pocket. It’s still a good idea to have a healthy supply of blades in the toolbox. They won’t break the bank either; a 100-blade kit, which is basically a lifetime supply, can be had for less than $10.

There are also a number of two-blade models available, like the Bostitch Twin Blade and the CH Hanson FlipKnife ($13), but these are overkill for general around-the-house use. What sets them apart is the ability to extend two different blades out of the same knife (though not at the same time) in case you need to use a hooked blade and a straight blade for the same project. As one would imagine, these tools are larger than normal to accommodate the added mechanisms and are geared towards professionals.

Know the laws

Finally, it’s of paramount importance that you understand your state and local knife laws before purchasing a knife, especially one that you intend to carry in your pocket or hooked to your belt. Some cities and states have extremely strict laws concerning the ownership and open carry of knives. As the Amazon product page of one Snap-on utility knife put it, “Sales of knives is prohibited or restricted in the following states: AL, FL, ID, KS, MA, MD, ME, MS, NC, NY, OH, OK, RI, TX, VI, WA, WI, WV.”

New York and New York City have very tight knife regulations, to the point that Home Depot will not ship a Fastback to the state. It’s a little unclear what the specifics of the law are regarding folding knives, but keep in mind that many knife enthusiasts feel that carrying a knife in NYC is something to be very cautious of and probably not worth it.

Wrapping up

The Milwaukee Fastback II is the ideal utility knife. Its ergonomic handle provides a high level of control which translates into safety. The blade change is easy, and so is the one-handed open and close. The blade storage is nice too. But if blade storage isn’t something that you’re concerned about, the original Fastback is a little cheaper.


1. Amstutz also looked at the DeWalt folding knife, but to operate that knife, you need to unfold it and then use a thumb slide to reveal the blade. This dual functionality makes it something of a hybrid between the two styles. We didn’t test this tool because with the other options out there, the double maneuver to expose the blade is unnecessary. Jump back.

2. A variation on this theme is the knives with auto-retracting blades, like this Wiss knife. Once the blade is engaged in a cut, some kind of trigger is tripped so that as soon as there is no longer any tension on it, it snaps back into the body of the tool. Theoretically, this happens as soon as the cut is completed, but there is at least one Amazon review saying that you need to apply constant pressure for the entire cut or the blade retracts before you’re finished. So if you pause to adjust your hand mid-cut, the blade retracts. Jump back.

3. Many people, Lyman included, prefer to carry a traditional knife as a daily tool. His preferred daily carry knife is the Benchmade Mini-Griptillian ($90) which he reviewed here. As he told me, “I’m snooty on the daily carry front. . . somehow a utility knife isn’t refined enough for me.” But others, like myself, prefer utility knives for their disposable blades. They always have a nice edge and I never have to think for even a second about blade maintenance. With my construction background, I also live a fairly aggressive DIY lifestyle, so traditional blades don’t last very long in my pocket. Jump back.

    How do you hang this up on a peg-board? Or tool-box only?

    • Doug Mahoney

      Peter, that’s a great point to make. The Fastback has no designated spot for a pegboard hanger, but you can hang it off the gut hook if need be. I just tested this out and it seems to work fine. It does put the blade in contact with the hanger, so there’s the change of damaging the blade, but if you’re careful about it, there should be no problems. You also might be able to use the belt hook. Like I said in the piece, it’s pretty springy.

      • PeterLLLLL

        Thanks, I’ll have to try to remember to check it out the next time I’m at Home Depot.

  • Bobby Draper

    Love this article. Was looking for a new knife for my tool bag and lacked the time to do an all-out comparison. I would really love a multi-tool/pocket tool breakdown like this. I got a Gerber Multi-Tool a few months ago and the pliers bent the first time I used em. Been scared to waist more money since. I know Leatherman cant be the best out there.

  • PatrickTulskie

    My experience with Irwin fold up utility knives has been less than stellar. Namely, the knives are difficult to open with gloves on and the blade is really loose in the holder. How secure is the blade in the Milwaukee? It seems to be a similar locking mechanism to the Irwin…

    • Doug Mahoney

      Patrick, I completely understand what you’re saying about opening with gloves on. The Irwin is definitely tricky. It’s strange because it seems that with a few small design changes (like a thumb stud), it could be a lot easier. This is also another high point for the Milwaukee. Yesterday, I had no problems using the knife with massive winter gloves on. As long as you can depress the release button, you can open it with no problems.

      Regarding the blade security, there was a standard amount of wiggle throughout the blades, even the retractables. To look more closely at the spectrum, the Milwaukee is on the tighter side and the Irwin is on the looser side, so if that’s a sticking point for you, I think you’ll be more satisfied with the Milwaukee. My guess is that the wiggle is there to accommodate for discrepancies between all of the different blade manufacturers.

  • Danette Jeoffroy

    Maybe for the BESSEY knife the D-BKPH would have been a better choice to review. It is a folding knife with blade storage for 5 blades (included). Just a thought :)

    • Doug Mahoney

      Danette, I did see that one in my research. The blade storage does look good, but with the two-handed close and the two-part blade change, I’d still go with the Milwaukee. I do like that little thumb rest area though. The Greenlee that I tested had that and I thought it was a pretty slick detail.

      • Danette Jeoffroy

        Fair enough!! Thanks for the reply :)

    • PatrickTulskie

      I had one of those in my workshop for probably 6-7 years that I rarely used because off the off-set blade. I just took it out the other day because I couldn’t find my other knife and I noticed that the black portion of the handle had separated and looked like it was like melting (it’s about 50 degrees in my work shop right now). There was an oily looking substance coming out of it that got all over everything in my drawer. I did look and make sure there were no chemicals or stuff spilled on it – the mess definitely came from the knife handle. Just be careful where you leave it.


    I use the Craftsman branded version of the TurboPro utility knife and love it dearly. I suppose it is a bit more work to operate, but I can take that when I am using it or replacing blades on-the-fly. I also really love the erognomics of the TurboPro. I usually use it with work gloves on and the oversized features really come in handy (pun intended). Lastly, the bottom bit can be used as a rudimentary bottle opener and can bash things effectively, like an attacker’s dome.

  • JacquelynnMorgan

    We can utility for the Knife in anywhere.

  • MisterWhiskey

    I’m not a fan, generally, of utility knives. Pocket knives work for me, I can sharpen them as needed, and the sheer range of them means I can carry a small Gerber EVO in addition to a larger Bolt-Action depending on what I think the day is going to be like.

    I suppose my position is really disposable versus nigh-heirloom quality. I’m certainly not intimidated by sharpening or even worrying about the blade surviving — it’s a tool, use it.

  • Jon Miller

    I just got the email today that mentioned this article. It’s funny because I just bought the Fastback II this past week. I can’t believe I’ve wasted money on other designs. This is the most solidly built, easy to use, and comfortable utility knife I’ve ever seen/held/used/owned.

    You should have seen the look on my wife’s face last night when I pulled it out to cut an event wristband off of my son’s arm. It said, “Are you nuts?! Don’t use a razor blade near his wrist! Grab some safety scissors!” But before she could even say anything I had slipped the slot of the knife over the wristband and had it off of him without extending the blade. So smooth.

    When I am actually using the extended blade it flicks out like a switchblade. It flicks back just as effortlessly.

    My only, very minor, issue with it is that it isn’t quite as smooth if I clip it on the left side of my belt. It’s only natural for me without brief fumbling if I have it on the right, and that’s where I keep my tape measure. Doesn’t feel right to have them together. But I like this enough that the tape measure is going to have to adapt.

    • tony kaye

      Thanks for the feedback!

  • Eric Lofgren

    I keep a utility knife in my shop apron/toolbelt. Every knife I’ve had that doesn’t come apart (like the cheap clamshell hardware-store variety does) has eventually gotten clogged with sawdust and rendered unusable until several painstaking minutes are spent unclogging it, usually with a nail and the corner of a combination square. How will your choice do in this environment?

    • tony kaye

      This one is extremely easy to take apart and clean should you feel the need. Here is what the commenter below you had to say about it (it’s right up your alley)-

      “I can’t believe I’ve wasted money on other designs. This is the most solidly built, easy to use, and comfortable utility knife I’ve ever seen/held/used/owned.”

  • ottothecow

    I still love the classic Stanley knife.

    Being able to expose only a limited amount of blade is very useful. If you want to open boxes without damaging the contents, just extend the blade to the first click and you can’t possibly cut any further. Also works for scoring materials that you don’t want to completely cut through–just extend the blade as far as you need.

    Yeah, it takes a screwdriver to change the blade and yeah, it doesn’t have a belt clip…but they cost $3-4, I only change the blades a few times a year at home (and it is a whopping single screw), belt hooks aren’t as comfortable in the hand, and it is hard to beat the reliability and durability of that design.

    I don’t even know what you mean by offering “the most rudimentary of safety features”–the blade retracts and stays there. No need to worry about how to lock the folding mechanism in place so that it doesn’t collapse, no need to worry about how to hold the extra blades so they won’t fall out. The Stanley Knife just works.

  • Andrew Ross

    Yeah, these folding utility knives are ok if you don’t have a tool belt and so, need a belt clip. Otherwise they are bulky and slow. For someone that uses a utility knife for everything under the sun and needs a sharp blade often, like carpenters for example, there is one utility knife to own; the Stanley quick change model 10-499 hands down. It is as slim as anything out there holds 6 extra blades and nothing changes blades faster or easier. $6-$7 at home depot. There is no substitute. I have tried dozens and most leave me rolling my eyes.
    That said, I want to repeat that if you do not wear a belt I can understand the need for a belt clip. However, these tuck nicely into the side pocket of carpentry type jeans or a back pocket near your wallet. I own a couple of the folding models and they stay in the house in the junk drawer where they will get some use from time to time.

    • tony kaye

      My last one of those fell apart on me after leaving the the bed of a truck for a few days in the rain/sliding around. Never again!

      • Doug Mahoney

        Yeah, I’ve never had luck with those either. I’ve owned a couple over the years and on one, the blade storage compartment loosened to the point where I couldn’t keep it closed. On the other, the blade would slip out of the nose of the knife during any moderate cuts, like drywall. For that style of knife, I much prefer the Milwaukee Slide Open (not the Fastback).

  • caltemus

    Have you ever used the Stanley 10-810? I bought one after borrowing one from someone in the shipyard that had used it for several years, and the well worn tool functioned as well as my new one. It has a nice pocket clip that could be deeper carry but is removable. It’s an all metal design that has a nice weight. It is easy to use with one hand but is aimed more at opening and closing it with your right hand.
