A good utility knife can do just about anything — from cutting boxes open and slicing through carpet to cutting perfect lines into drywall or making crafts.
With an ergonomic all-metal handle, an intuitive and easy-to-use folding design, quick blade changing, and a built-in wire stripper, the iconic Milwaukee Fastback 3 is the last utility knife you will ever need.
The knife may be the oldest tool known to man, and despite thousands of years of technological development, a good blade remains one of the most versatile items you can own. But your standard steel pocket knife — while great for EDC — isn't always the best tool for cutting. When it comes to making precise, arrow-straight cuts, there's no better instrument to reach for than a good utility knife.
Often simply referred to as a "box cutter," the utility knife is a versatile and indispensable tool suited for a wide variety of applications. For carpet, leather, drywall, flooring, crafting projects — and, of course, cardboard boxes — a good utility knife is hands-down the best tool when you need to make a smooth, clean cut.
Along with super-sharp razor-like blades that are perfect for precision cutting, utility knives offer other advantages over traditional folding and fixed-blade knives: They don't need sharpening (as you simply replace the blade when needed), the blades are typically retractable, the grips are considerably larger, and a smaller length of sharpened edge is exposed for safer cutting. Modern folding utility knives also offer the same portable convenience as a pocket knife.
Utility knives are simple tools and the good news here is that you don't need to spend a lot of cash to get a really good one. They're not all made the same, however, with a number of different types and designs available today. We've done the research to sort out the five best utility knives you can buy, from sturdy everyday-use models to ones built for more specialized tasks. Even better: Each of our picks rings in at less than $20.
Here are the best utility knives you can buy:
Read on in the slides below to check out our top picks.
The best utility knife overall
Why you'll love it: A solid and ergonomic all-metal body, convenient folding design with pocket clip, quick and tool-less blade swapping, and handy wire strippers make the Milwaukee Fastback 3 the best utility knife.
When looking for a good utility knife, you naturally want something that is durable, provides a safe and comfortable grip, and has a design that is convenient to operate with easy-to-change blades. Utility knives are pretty simple pieces of kit, but our pick, the Milwaukee Fastback 3, has a few design features that put it well ahead of the competition.
Firstly, everything about the Fastback is dead simple to use: The folding mechanism locks tightly but can be opened with the press of a button and a flick of the wrist, blade changes are quick and simple with no tools required, and it's got a nice sturdy pocket clip for safe and easy carry. Its all-metal construction means it'll last for a lifetime, too, and the ergonomically contoured handle provides a secure and comfortable grip with a finger indentation to keep your hand from slipping.
The Fastback also has two additional tools built right in: A small wire stripper placed towards the front of the blade and a larger gut hook on the back of the handle for stripping thicker wires. This gut hook is also ideal for quickly cutting things like twine or for opening bags without having to reach for another tool. The Fastback 3 contains a swing-out compartment that can store up to four spare blades as well, and it has the extra ability to lock the blade at 45 degrees for a more aggressive downward cutting angle.
If there's one thing that some buyers might consider to be a drawback, it's that the Milwaukee Fastback is no longer made in the US. This isn't by itself a bad thing so long as quality control is there, and many happy owners report that the Fastback remains a solidly built tool that should last a long, long time. And with a price tag of around $18 for the Fastback 3, it's hard to fuss about details like this.
Pros: Sturdy all-metal construction, the folding mechanism locks tightly while offering easy one-handed opening, built-in wire stripper and gut hook, the ergonomically contoured handle is comfortable and safe, quick and tool-free blade changing, and the Fastback 3 has built-in blade storage
Cons: No longer made in the US
The best budget utility knife
Why you'll love it: Sometimes all you need is a tool that's cheap, simple, and well-built, and the Stanley Classic does everything you need a utility knife to do for just $5.
Good utility knives aren't super costly tools. Even the more expensive version of our top pick, the Fastback 3, will set you back less than $20. But sometimes, all you need is a cheap, simple tool to get the job done, or maybe you just want something inexpensive enough that you can buy a couple to keep around so you've always got one handy when you need it.
No utility knife fits this bill better than the aptly named Stanley Classic. Your parents and grandparents likely have one or two of these lying around somewhere, and the design hasn't changed much over the years. This is a simple, no-frills, heavy-duty utility knife made right here in the United States, featuring a large and sturdy six-inch metal handle (which you can store spare blades in) with a thumb-activated three-position blade slide.
Just as attractive as its all-American build quality is its $5 price tag, which would be impressive even if the Stanley Classic wasn't still manufactured in the US.
The only drawback we can find is that, being an older design, the handle must be taken apart via a single Phillips head screw in order to change blades. This is easy to do and, given the knife's incredible value, isn't something to squint too hard at. At this price, you might as well buy a couple.
Pros: Made in the US, sturdy and large metal handle with a built-in spare blade compartment, secure three-position blade slide, and it's an incredible value at only $5
Cons: Handle must be taken apart to change and store blades
The best snap-off utility knife
Why you'll love it: If you're tired of frequently swapping out dull blades, then the Japanese-made Olfa LA-X utility knife offers the convenience of a one-piece blade with snap-off sections and a locking slide that gives you a longer working edge.
Given Japan's long history of blade-making, it should come as no surprise that some of the sharpest knives and razors today come from this part of the world. Olfa is a household name in the niche market of utility knives, making blades that are notoriously sharp and cut extremely well. You'll find more than a few online reviews where the user learned this first-hand, the hard way.
Olfa makes a number of different snap-off utility knives, but our favorite is the LA-X due to its large cushioned handle with anti-slip rubber grip inserts, easy-to-use blade locking mechanism, and metal pick located at the back that can be used for quick tasks like prying off paint can lids (among many other things). This little pry bar will also help you avoid the temptation of using your blade to pry things open when you shouldn't.
What's most notable about Olfa knives, however, is the heavy-duty one-piece blades which are cut into eight sections that you can snap off when the exposed edge gets dull, precluding the need for frequent blade changes. Another advantage of this long snap-off blade is that the Olfa's LA-X slide lock lets you extend the blade itself out a bit further, giving you a larger working edge than is possible with a standard utility knife.
The Olfa LA-X is cheap, too, and replacement blades are also pretty inexpensive. A number of snap-off utility knifes are designed with disposable handles, but we find this to be unnecessarily wasteful when you can get the Japanese-made Olfa LA-X for around $10.
Pros: Made in Japan, sturdy fiberglass handle with anti-slip rubber grip, the snap-off blade prevents the need to change blades when the edge gets dulled, and the locking blade slide can be extended for a longer working edge
Cons: No storage compartment for spare blades
