This is an extremely versatile Swiss Army knife in the classic SAK tradition with 1 large and one smaller blade, standard screwdriver, Phillips head screwdriver, bottle and can opener, scissors and more all compressed into a remarkable flat profile with the Wounded Warrior Project logo.
Gerber Curve Multi-Tool
There are “futuristic” looking keychain knives and then there’s the Gerber Curve. The Curve lives up to its name while putting its curves to work in a way that allows you to bring extraordinary force to bear on the cutting surface. In that way you’re able to get the absolute maximum out of the 1 1/4 inch blade. But the Curve is more than just a tough, light, durable stainless steel blade. It also features both small and medium standard screwdrivers, a Phillips head screwdriver, bottle opener and more. If you want your EDC to be both practical and stylish this is the keychain knife for you.
The Cinder is one of the more comfortable keychain knives you’ll have a chance to hold. The stout design of the 3Cr13 1 2/5 inch stainless steel, stonewashed blade and robust, contoured handle mean you can really lean into the task at hand without fear. There’s a stainless steel lanyard notch that also doubles as a glass breaker and a bottle opener so that you can celebrate with a frosty brew after you’ve extricated yourself from that overturned wreck. The whole thing folds up tight and flat into the glass nylon handle and will slip neatly into your pocket.
Gerber STL 2.0
The blade of the STL is forged from surgical grade 7Cr17MoV (say that 3 times fast!) stainless steel and features a small cut out intended to aid one-handed opening. The blade, which locks in place securely when opened, gives the STL an overall length of 5 1/8 inches, which means it’s definitely flirting with the upper limits of the keychain knife. But a keychain knife it is and one for which you’ll find myriad applications from self-defense to opening packages to gutting fish. Limited lifetime warranty included.
Buck Knives 0425
The Mini Buck Folding Knife is a classic keychain knife with a relatively short 1 7/8 inch 420 high carbon stainless steel drop point blade, a black Valox handle that’s big enough to grasp comfortably and a large keychain ring so you’re never without it. The high carbon blade retains a nice sharp edge and resharpens easily when need be. It has a secure lockback feature that protects your fingers from accidental closing and is corrosion resistant so you can take it with you anywhere. At 2 7/8 inches when closed the Mini Buck slips easily into the pocket of your jeans or tactical pants.
Buck Knives 283
The 283 Nano Bantam keychain knife from Buck eschews the strict utilitarian profile of their Mini Buck Folding knife in favor of the more imposing and, frankly, pleasing profile of the standard folding pocket knife (complete with nail notch on the blade). Also pleasing is the fact that this keychain knife tips the scales a very modest .6 oz and that the blade is composed of the same high carbon 420 steel of the best keychain knives out there. The red, contoured handle feels just right in your hand and with the secure lockback in place you don’t ever have to worry about blade related mishaps.
The SOG Centi I keychain knife sports a no-nonsense design that maximizes the cutting edge and provides a firm, safe grip no matter the application. The 1 3/8 inch high carbon blade is hollowed out in the center to reduce weight and there’s a generous hole at the butt end of the handle for attaching it to your keychain; which is really where this knife belongs. It’s smaller than it appears in pictures but just as dependable and well-built as all of SOG’s other tactical gear. If there’s one drawback to the Centi I keychain knife it’s the lack of a locking mechanism. Other than that it’s all good.
The second of our keychain knives that’s built to resemble a key the Guardman Keychain Folding knife sports a long slender blade that’s great for a number of simple tasks but not ideal if you need to lean into the work. That said it’s a great little keychain knife that folds up to a neat 2 5/8 inches and weighs virtually nothing. Use it for myriad light tasks from opening boxes to cutting fishing line, stripping wire or even cleaning your nails. When you’re done with it fold it up and forget about it. Ideal for pros or do-it-yourselfers.
Tonife Fixed Blade
Tonife takes a slightly different approach to the keychain knife and in the process answers the question “Why can’t a keychain knife be full tang?” We love the way this pocket rocket looks and feels. It’s a pleasure to hold and the 1 3/4 inch curved blade optimizes the cutting surface. With the full tang construction you can use every micron of that surface and really lean into your work without ever having to worry that the blade might give way. The handle is made of rugged G10 material that won’t rot or corrode and allows the knife to retain a lightweight overall profile. Just don’t expect to ever carry this baby on your keychain.
The Promithi 151105 is an extremely effective keychain knife that behaves like a much larger knife. It’s only 2 5/8 inches long when close and flat as a piece of cardboard so once you hook it up to your keychain you’ll likely forget it’s there until you need it. The aggressive forward arc of the knife along with the wide 5CR16 stainless steel blade means you can bring all kinds of force to bear on whatever you’re doing. The broad handle allows you to get a firm grip whether you’re opening boxes or carving tent poles. There’s a nice big lanyard hole so the keychain knife will lay flat in your pocket.
The StatGear Pocket Samurai goes in the opposite direction from those keychain knives that embrace curvilinear design. The hard and fast geometry of the Samurai evokes timeless Asian design cues while retaining the type of superior functionality you’d expect from the best keychain knife. The tanto blade is sharp as a razor and the fact that it comes with a pocket clip means you don’t have to confine it to your trouser pockets. You can keep it in the pocket of your work shirt for quick, easy retrieval. The blade is 440C carbon stainless, the anodized aluminum handle comes in 6 different colors and the knife carries an unconditional 90 money back warranty.
Small Pocket Knife
Now here’s something you don’t see every day. A tactical money clip that’s also a first class keychain knife. While the versatility of this implement is impressive don’t expect it to win any awards for “most beautiful keychain knife”. It’s bare bones simple; intended to be lightweight and effective. The 2 1/8 inch blade is fashioned from 420 high carbon steel so you’ll always have a razor sharp blade and that blade locks open to eliminate the chance of mishaps. There’s a nice big lanyard hole so you can attach it to your keychain easily and the money clip keeps a fair number of bills safe and secure. If you’re into minimalist design you’ll love the Grand Way.
Old Timer 1OT
This is about as close as you’ll get on this list of Best Keychain Knives to your grandfather’s keychain knife. It’s got a deliberate throwback look that never goes out of style and it’s a nice compact size so carrying it on your keychain is not the impossible dream as it can be for some keychain knives. It features an imitation wood polyoxymethylene thermoplastic handle that’s made to last and the 1 5/8 inch blade has the familiar nail notch so you can open it in a hurry. The blade is fashioned from 400 carbon steel so it will always sharpen up fast and the whole thing weighs less than an ounce. Throw in the fact that it’s around 10 bucks and it makes a great stocking stuffer come holiday time.
SOG Micron Folding Knife
The Micron from SOG features a 1 1/2 inch high carbon blade with a tanto shape that comes to a fairly aggressive point. That blade also has a serrated section on the spine that provides something almost no other keychain knife does: the ability to hack through small branches, hard plastic and myriad other things. The blade locks open securely to prevent possible mishaps and the anodized stainless steel handle provides a remarkably firm grip for such a small knife. The Micron is flat enough and light enough to be easily carried on your keychain and the knife itself carries a limited lifetime warranty.
The Kubotan keychain knife was developed as a self-defense weapon by Takayuki Kubota in the late 1960s. In the case of this Kubotan it has a 4 inch stainless steel blade that is concealed inside an anodized black aluminum handle. At the butt end of the handle there’s a generous sized loop for attaching the knife to a keychain for innocuous transport. While there are no doubt some precision type applications you can use the Kubotan keychain knife for it is first and foremost intended as a discrete self-defense item. When clipped to your keychain it appears to be a marker of some kind but when opened it reveals itself to be an effective self-defense knife, though some practice will likely be required to master it.
