It’s a rugged knife that can take its fair share of rough use thanks to the blade cutout for added flexibility. Despite the small overall size of the blade, it’s exceptionally easy to hold the ergonomic handle. Unless you have very large hands, you’ll have no trouble fitting the knife in your hand and not have to worry about your finger slipping onto the blade.
The handle’s surface is texture to give you slip-resistance and there are grooves and molds to better fit the profile of your hand. You’ll find the blade comes very sharp out of the box and holds its edge well enough. You’ll need to touch it up once in a while to get the most from it.

4 Things to Look for in a Great Keychain Knife
Buying a knife can be overwhelming with the plethora of excellent choices on the market. Will very little to differentiate many of the top-quality knives, it can be a real challenge to find the best value for money and a knife that suits both your needs and budget.
We’re going to take a look at some of the features we think are the most important to consider before buying a keychain knife. You’ll find some good pointers and tips to help you get the perfect keychain knife for you. Let’s take a look.
People don’t buy keychain knives to cut down trees, which is why choosing a keychain knife with a good balance between weight and functionality is essential. You should choose a knife that weighs under 2oz if possible. Slightly heavier is okay if your unique needs require a heavier knife – but you’d probably be better off getting a pocket knife in that case.
We always recommend staying under 3” in blade length. There are several reasons for this. Longer blades add a lot of the overall weight of the knife and this goes against our first pointer. Another reason is a legal one – many states and countries have a legal requirement that an EDC blade should be less than 3” in length. You should check your local laws before getting a keychain knife, especially if its blade is longer than 3”.
Some excellent Victorinox Swiss Army keychain knives meet both of the above tips – but add in a ton of versatility and functionality beyond a basic blade. Just be mindful of the weight and you’ll be good to go.
Stainless steel that’s highly resistant to corrosion is a must. Keychain knives are going to go almost everywhere you are, which is why they need excellent resistance and toughness. On the note of toughness, avoid steel that’s harder than HRC58 as it gets brittle and is prone to chipping and scuffing.
Frequently Asked Questions (FAQ)
Q: Can I Use a Keychain Knife as a Legal EDC Knife?
A: They’re a little on the small side to be relied on as a sole everyday carry knife. That being said, their smaller blade size and discreet profile mean they’re legal in most places. You need to check the blade size limit and related laws for carrying a knife around in public as they vary hugely from state to state and country to country.
Q: How Long Do Keychain Knives Last?
A: This depends on how well you take care of them. The biggest causes of wearing are rough use and poor cleaning practices. Learn how to clean and dry a knife and learn your knife’s limits.
Q: Can I Use These Knives for Piercing?
A: To an extent, yes, you can. Don’t go overboard. They aren’t designed with reinforced or particularly strong tips. They could buckle or break if you’re trying to pierce tough leather, for example.
You should have a good feel for what you’re looking for and the features that will best suit your style and needs. All that’s left now is for you to make your choice. If this is your first knife, don’t get caught up in the details.
