15 Best One-Piece Multi-Tools For EDC

Multi-tools are one of the greatest categories of everyday carry gear for their uniqueness and versatility. Some of them even pack in enough tools to completely replace the average toolbox. And their portability makes them much more travel-friendly than their single-function counterparts. Our only issue is that some of them have moving parts that can break with too much use.

While it’s a fairly simple to replace a broken folding multi-tool, there is also another option: get one without any moving parts. Nowadays, though, they aren’t quite ubiquitous enough to be called commonplace, there are a number of multi-functional tool options that work without any hinges, connection points, folding, or anything else. Though not invincible, these one-piece multi-tools are a great way to get a lot of functionality while mitigating the risk of breakable parts. And that’s why we’ve rounded up the 15 best one-piece multi-tools for the following guide.

Kershaw PT-2 Keychain Multi-Tool

Measuring up just barely longer than a standard-sized house key, Kershaw’s ultra-compact PT-2 keychain multi-tool packs a wallop to the tune of 8+ built-in features, including hex wrenches, screwdrivers, a bottle opener, and more. And since it is lacking a blade, it’s also TSA-compliant and, therefore, great for travel. For minimum impact to both your wallet and your pocket space, it’s hard to find something with as much functionality as this device.

Gerber Shard Keychain Multi-Tool

One of, if not the greatest keychain multi-tool of all time (both for its iconic design and remarkable size-to-function ratio), the Gerber Shard is a crowd-pleaser to be sure. It’s not packed with the most functionality, boasting just 4+ built-in tools, but at just barely over 3 inches in length, you couldn’t really ask for more. It helps, too, that it is made from titanium nitride-coated stainless steel, which is especially durable — a welcome factor considering that it will be on your keychain alongside all your other small gear.

CRKT Viva Multi-Tool

Envisioned by Long Mah, a noteworthy knife designer responsible for some truly impressive designs, the CRKT Viva is a superb small-form one-piece multi-tool. Looking like something out of a science-fiction movie, this stonewashed device boats over eight different functions, including multiple hex wrenches, a bottle opener, screwdrivers, a pry bar, and more. It also boasts a handy pocket clip, so you can keep it at the ready without having to dig around for it.

Leatherman Piranha 2 Multi-Tool

Leatherman is the king of multi-tools, that’s for certain. So it should come as no surprise that, while most of their offerings are the traditional folding type, they also make one of the best one-piece multi-tools on the market. Called the Piranha 2, this stainless steel pocket multi-tool is completely TSA-compliant, making it an excellent choice for travel. It also boasts more than seven built-in functions, including a number of wrenches, a hex driver (with an included dual-sided Phillips and flathead screwdriver bit), a box opener, and more.

Designed to mimic the appearance of a standard house key, both in overall form and size, this little USA-made device can hide away easily alongside the rest of your keys, while still offering 6+ built-in functions including a bottle opener, hex wrenches, and more. It helps, too, that it’s made from solid titanium, and therefore, both ultra-lightweight and remarkably durable. For a discreet one-piece multi-tool, you can’t go wrong with this one.

Tools: 6+
Size: 2.2″ L x 1″ W

TT Pocket Tools Chopper Multi-Tool

While there are a number of one-piece multi-tools that are small enough to fit on your keychain, few (if any) are quite as functional as the TT Pocket Tools Chopper. Just 2.25″ at its longest point, this marvelous made-in-USA device is built from sturdy stainless steel and boasts over 12 built-in tools — including wrenches, drivers, a bottle opener, and more. Truly, this little tool is one of the more impressive options out there, especially considering how compact it is.

Kizer Crocotool Multi-Tool

You could argue that most knives function fairly wonderfully as multi-tools, though they’re not always intended as such. However, if you want a one-piece multi-tool that’s got a solid cutting edge while still boasting intentional multi-functionality, there’s an answer to be found in the Kizer Crocotool. Built from stainless steel, this device has an actual, functional cutting edge alongside at least five other tools — which include wrenches, a bottle opener, a pry bar, and more. And once you’re done using it, you can stash it away in the included sheath for safe keeping.

Tools: 6+
Size: 4.25″ L

Purchase: $32

Tactica Gear M100 Multi-Tool

There is an argument to be made that the Tactica Gear M100 multi-tool doesn’t really qualify as one single piece, as it features a composite exterior (40% lighter than titanium while still being remarkably durable) with a stainless steel core. However, as it has no moving parts, we believe it still meets our expectations. Alongside its impressive construction, it also features over 20 built-in functions, is completely TSA-friendly, and still weighs just 1.6 ounces total. Just don’t get too excited about it looking like a keychain carabiner, as it doesn’t function like one.

Material: Composite Exterior & Stainless Steel Core
Tools: 20+
Size: 3.15″ L x 1.57″ W

Purchase: $32

Lever Gear Toolcard Pro

Forty+ functions built into a single one-piece multi-tool that’s small enough to fit inside your wallet is certainly something to be excited about. And it isn’t hurt one bit by the fact that it boasts a sturdy stainless steel construction. Or that it is completely TSA-compliant. Pair that with a wealth of helpful markings, an all-black colorway option, and a possible removable pocket clip, and the Lever Gear Toolcard Pro is one of the most impressive one-piece multi-tools ever conceived.

Material: 420 Steel
Tools: 40+
Size: 3.35″ L x 2.79″ W

The James Brand Halifax Keychain Multi-Tool

There’s no denying the sheer beauty in just about everything The James Brand makes, and their Halifax keychain multi-tool is no exception.

Boker Plus Cop Tool Knife

Emergency situations, like those encountered by first responders and law enforcement, require very different tools than those found in normal everyday life. As such, a one-piece multi-tool is hard to find for this crowd. But one does exist in the Boker Plus Cop Tool Knife. Made with a seatbelt cutter, glass-breaker tip, serrated knife edge, chisel tip, and sturdy G10 handle scales over a 440C stainless steel construction, this is a uniquely equipped device that’s an excellent go-to in the case of survival situations.

Material: 440C Steel & G10
Tools: 5+
Size: 6″ L x 1″ W

Purchase: $50

EDC Card Multi-Tool

The Levergear Toolcard might boast more (albeit unnecessary) functions, but the EDC Card one-piece multi-tool has got it beat hands-down when it comes to build materials and sturdiness. You see, this device is a bit thicker — though it can still fit into a normal wallet credit card slot — and built from military-grade S35VN blade steel. And that makes it a mighty choice for anyone who values toughness and durability. Even still, its 20+ functions are definitely nothing to scoff at, either. And it certainly doesn’t hurt that it’s TSA-friendly and made in America.

Material: S35VN Steel
Tools: 30+
Size: 3.25″ L x 2.06″ W

Purchase: $51

Hutan Pressure Tool

Most one-piece multi-tools are geared toward normal everyday life. Unfortunately, “normal everyday life” doesn’t appear to include the needs of those who take frequent off-roading or overlanding trips. Thankfully, if you do find yourself frequently behind the wheel of a 4×4 off-roader, there’s still an option for you: the Hutan Pressure Tool. Designed specifically for the needs of all-terrain automotive enthusiasts, this titanium tool features wrenches, drivers, and even a handy device that makes reducing your vehicle’s tire pressure a snap — perfect for hitting the trails.

Material: 8Cr13MoV Steel & G10
Tools: 8+
Size: 3.75″ L

Purchase: $89

Dango T01 Tactical Multi-Tool Wallet

Technically speaking, the Dango T01 isn’t actually a one-piece multi-tool. Rather, it’s a fully-featured USA-made wallet with a leather and aerospace-grade aluminum construction, a 12-card capacity, built-in RFID blocking, and more. But it does come with the brand’s stainless steel, removable MT02 multi-tool insert — which does qualify as a one-piece multi-tool boasting 14+ built-in functions. If maximizing your carry functionality while keeping your pockets uncluttered is high on your list of requirements, this might just be the ultimate piece of EDC gear.

Material: Stainless Steel, Black Leather, & 6061 Aluminum
Tools: 14+
Size: 4.375″ L x 2.625″ W
