The Best Utility Knives: 4 Compared (and One to Skip)
We compared four utility knives on mechanism, body material and blade storage, and found four different published blade lengths for a blade that is the same in all of them.
The short version
DeWalt's DWHT10319 is the pick: a metal-bodied retractable with three-position blade retention and storage for five spare blades, at 0.5 lb. The DWHT10991 Push and Flip is the value buy if you carry a knife in a pocket rather than a bag, opening one-handed with an aluminium body at 0.29 lb and a reversible deep-carry clip. Craftsman's CMHT10353 folder is the depends pick: same idea, all-metal, and the only folder here with spare blades stored inside it, though its spec table lists a piece count that does not match the product name. Skip the CMHT10588 quick-change two-pack. Its own spec table lists a 10 in. height and a 0.81 in. length on a pocket knife, gives no unit for blade length, and its piece count of 8 does not match anything in the description. Best for: anyone who cuts drywall, carpet, cardboard or insulation and wants the mechanism to be the reason they chose.

What mattered most
- Mechanism
- Published blade length
- Body material
- Onboard spare blades
- Pocket clip
- Weight
Every utility knife on this page takes the same blade. The standard trapezoid utility blade has been dimensionally interchangeable across brands for decades, which means the blade is not what you are choosing. You are choosing a mechanism, a body and how the thing carries. That should make the spec sheets simple, and instead the four blade length figures published for that one standard blade read 2.44 in., 31 in., 1.25 and 1. We compared what is actually different.
Metal body, three-position blade retention and five spare blades on board, which is the full job in one tool.
Best for: Anyone whose knife stays in a tool bag and gets used all day, where depth control and onboard blades matter more than pocket carry.
- Metal body with a bi-material grip, so it survives being dropped and being stood on.
- Onboard storage for five spare blades, which is where spare blades actually belong.
- Three-position blade retention gives real depth control for scoring rather than cutting through.
- 0.5 lb and 8.6 in. long, substantial enough to hold firmly without being a burden.
- Heaviest knife here at 0.5 lb, twice the weight of either folder.
- A retractable slide is slower to deploy one-handed than a push-and-flip folder.
- Blade length is listed as 2.44 in., which is the exposed length rather than the standard blade's overall dimension.
- No pocket clip, so it lives in a bag or a pouch rather than on you.
Opens one-handed, weighs 0.29 lb, and clips deep in a pocket, which is why it gets carried and used.
Best for: Anyone who wants a knife on them rather than near them, and who opens a lot of boxes and cuts a lot of packaging one-handed.
- Push-and-flip opening works one-handed, which matters when the other hand is holding the material.
- Aluminium body at 0.29 lb, light enough to forget you are carrying it.
- Reversible deep-carry wire pocket clip, so it rides low and either way round.
- Blade lock plus a push-up quick change lever, with a slide-and-click blade insert.
- No retracting blade, so the mechanism is open or closed with nothing in between.
- No onboard spare blade storage, unlike the DWHT10319 and the Craftsman folder.
- The spec table lists a blade length of 31.0 in. on a knife that is 8.3 in. long overall, which is a data error.
- A folder has a pivot, and a pivot is one more thing to get packed with drywall dust.
An all-metal folder with spare blades stored inside it, which neither DeWalt manages, on a listing that will not tell you exactly what arrives.
Best for: People who want a pocket folder that carries its own spare blades, and who are willing to find out what is in the box when it arrives.
- Drop-down storage for three spare blades in a folding body, which the DeWalt folder does not offer.
- All-metal construction with a push-button opening and a tool-free blade change.
- Reversible pocket clip and 0.29 lb, matching the DeWalt folder's weight exactly.
- Backed by Craftsman's full lifetime warranty.
- Blade length is listed as 1.25 with no unit given anywhere on the page.
- The spec table lists Piece Count as 2 and Individual or Set as Set, while the product name describes a single knife with 3-blade storage.
- No retracting blade or depth positions, same limitation as the DeWalt folder.
- No warranty terms beyond the full lifetime claim, and no stated blade retention mechanism.
A retractable with three cut depths, sold in a two-pack, on a spec sheet that does not describe the object in the photo.
Best for: Almost nobody as a first choice. The mechanism is right and the published specification does not describe it, which is a bad combination when you cannot handle the tool first.
- Three cut-depth positions and a retractable blade, which is the mechanism we prefer for bag use.
- Integrated blade storage in the handle and an interlocking nose for blade security.
- Made in the USA with global materials, with an all-metal handle.
- The spec table lists Assembled Product Height as 10.0 in. and Length as 0.81 in., which are transposed.
- Blade length is given as 1 with no unit.
- Piece Count is listed as 8 on a product sold as a 2-pack, with no explanation of what the other six items are.
- 0.75 lb for the pair, and buying two knives to get one is the wrong way round.

How we judged the field
Five things decide a utility knife, and none of them is the blade. Mechanism comes first: retractable knives give depth control and protect the edge with a slide, folders give one-handed pocket carry and a pivot to keep clean. Second is body material, because a metal knife survives being stood on and a plastic one does not. Third is where the spare blades live, since a knife with onboard storage means you never have a dull blade and no replacement. Fourth is how it carries, which decides whether you have the knife when you need it. Fifth is the blade change, which every knife here now does without tools but which varies in how safe it feels.
The field splits into folders and retractables, and the split is about carry rather than cutting. Folders live in a pocket on a clip and open one-handed. Retractables live in a bag and offer detent positions for controlling how far the blade projects. Nobody has combined the two convincingly, so the choice is genuine. We took one of each from DeWalt, then both Craftsman equivalents, which also happen to be the two products in this comparison sold as multi-packs.
DeWalt DWHT10319 Retractable Utility Knife - buy
The DWHT10319 is the knife to buy if a knife is a tool rather than something you carry. It has a metal body with a bi-material grip, which is the combination that survives a drop onto concrete and a boot on a bag. It stores five spare blades onboard, which sounds like a small thing until the day you are on a roof with a dull blade. And it has three-position blade retention, which is the one genuine functional advantage a retractable has over a folder: you can set the blade to project a few millimetres and score drywall paper without cutting through the board. At 0.5 lb and 8.6 in. it is the biggest and heaviest thing here, and there is no pocket clip, so this is a bag knife. DeWalt lists the blade length as 2.44 in., which is the exposed cutting length rather than the blade’s full dimension. Buy it if the knife lives with your tools.
DeWalt DWHT10991 Push and Flip Folding Utility Knife - buy
The DWHT10991 is the knife you will actually have on you. Push-and-flip opening genuinely works one-handed, which is the whole argument for a folder, because the situation where you want a knife usually involves your other hand holding the thing you are cutting. The aluminium body keeps it to 0.29 lb, and the reversible deep-carry wire clip means it sits low in a pocket either way round. DeWalt has also thought about the blade change: a push-up lever that is hard to trigger by accident, and a slide-and-click insert that does not need the blade to be pressed home by hand. The compromises are structural. There is no retracting slide, so no depth control, and no onboard spare blade storage. And the spec table lists a blade length of 31.0 in. on a knife that is 8.3 in. long overall, which is a plain error rather than a specification.
Craftsman CMHT10353 Folding Utility Knife with 3-Blade Storage - it depends
The CMHT10353 is the interesting one, because it does something neither DeWalt does: it is a folder with three spare blades stored inside it. That combination, pocket carry plus onboard blades, is what most people actually want, and Craftsman got there with an all-metal body, a push-button opening, a reversible clip and a tool-free change, at 0.29 lb, matching the DeWalt folder exactly. It is backed by a full lifetime warranty. Then the listing gets in the way. Blade length is given as 1.25 with no unit anywhere on the page. Piece Count reads 2 and Individual or Set reads Set, while the product name describes a single knife with 3-blade storage, so it is genuinely unclear whether you are buying one knife or two. That is the reason this is a depends rather than a buy: the tool looks right and the page will not tell you what arrives.
Craftsman CMHT10588 Quick Change Utility Knife, 2 Pack - skip
The CMHT10588 is the one to skip, and it is a shame because the mechanism is the one we prefer. It is a retractable with three cut-depth positions, an all-metal handle, integrated blade storage and an interlocking nose for blade security, made in the USA with global materials. On paper that is the DeWalt DWHT10319’s feature set at a lower price. The problem is that the published specification does not describe the object. Assembled Product Height is listed as 10.0 in. and Assembled Product Length as 0.81 in., which are transposed. Blade length is given as 1 with no unit. Piece Count is 8 on a product sold as a two-pack, with nothing on the page explaining what the other six items are. When you cannot handle a tool before buying, the spec sheet is the tool, and this one has not been checked.
DeWalt DWHT10319 Retractable Utility Knife vs DeWalt DWHT10991 Push and Flip Folding Utility Knife: which should you buy?
The DWHT10319 and the DWHT10991 are the same brand answering two different questions, and the honest way to choose is to ask where the knife will be. The retractable is heavier at 0.5 lb, has no clip, and holds five spare blades. Its three detent positions are a real capability: setting a shallow projection to score drywall paper, a medium one for carpet, full extension for cutting through. A folder cannot do that at all.
The folder is 0.29 lb with a deep-carry clip, opens one-handed, and is therefore the knife that is with you when a box needs opening or a strap needs cutting. That availability beats capability more often than people expect, because the best knife is the one in your pocket rather than the one in the van. If you are buying one knife and you work out of a bag all day, take the retractable. If you are buying one knife and you want it on you, take the folder. Buying both is not an unreasonable answer, and between them they cost less than a lot of single tools.
What to look for
- Mechanism first: retractable gives depth control from detent positions, folding gives one-handed pocket carry, and no product here does both well.
- A metal body: every knife in this comparison has one, and it is the difference between a tool that survives a bag and one that cracks.
- Onboard blade storage: a knife that carries three to five spares means you change a dull blade instead of forcing it.
- How it carries: a reversible deep-carry clip is what turns a knife into something you have on you rather than something you fetch.
- A blade change you can do safely: every knife here is tool-free, but check that the release cannot be triggered while the blade is out.
- Whether it is a multi-pack: two of the four here are sold in pairs, which is good value only if you wanted two.
Our final take
Once you know every knife on the shelf takes the same blade, the decision simplifies to mechanism, body and carry. The DeWalt DWHT10319 is the pick for a bag knife: metal body, five blades on board, and three detent positions that let you score rather than cut through. The DWHT10991 is the pick for a pocket knife, one-handed and clipped deep at 0.29 lb, and it is the one that will get used most because it is the one you will have. The Craftsman folder does something clever by putting spare blades inside a folding body, and then leaves you guessing whether the box holds one knife or two. The CMHT10588 has the right mechanism attached to a spec sheet listing a 10 in. height on a pocket tool, and that is the one thing you cannot check from a photo.
Questions, answered
Are utility knife blades interchangeable between brands?
For the standard trapezoid blade, yes. It has been a common pattern for decades, and a box of blades from one brand fits a knife from another. That is why the blade is not the thing you are choosing when you buy a utility knife. It also means the sensible way to buy is to pick the mechanism you like and then buy blades on quality and price separately, rather than assuming a brand's blades belong in that brand's knife.
Why do these four knives publish four different blade lengths?
Because the field is being filled in inconsistently rather than measured. DeWalt lists 2.44 in. for one knife and 31.0 in. for another that is 8.3 in. long overall. Craftsman lists 1.25 for one and 1 for the other, both without a unit. All four take the same standard blade. Read the blade length row as an indicator of how carefully the rest of the page was filled in, and read nothing else into it.
Retractable or folding: which should I buy?
Retractable if the knife lives in a bag and gets used constantly, because the slide gives you depth control and the blade is protected without a pivot to jam. Folding if the knife lives in a pocket, because a folder with a clip is a knife you have on you and a retractable in a bag is a knife you have to go and get. The one real functional difference is depth control: a retractable with detent positions lets you score a surface without cutting through it, and a folder cannot.
What is a bi-metal blade and is it worth the extra?
A bi-metal blade welds a high-speed steel cutting edge to a more flexible spring steel back. The edge holds longer than plain carbon steel and the back resists snapping when the blade is twisted in a cut, which is the failure mode that sends a blade fragment flying. For cutting drywall and cardboard the difference is modest. For anything where the blade gets levered or twisted, such as cutting roofing or thick rubber, it is worth the money.
How do I change a blade without cutting myself?
Every knife here changes blades without tools, which is the improvement of the last twenty years. The rule that matters is to make the blade safe before you touch the mechanism: retract or fold the knife first, then release the carrier, and handle the old blade by the blunt spine. Used blades belong in a purpose-made blade disposal container or a taped-up rigid container, never loose in a bin, because bin bags do not stop them.
