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).

Q: What Are Keychain Knives Used For?
A: If you’re smart about how you plan out your EDC, then you know one thing: you can never have enough usefulness out of every single object on your person.

It’s a scary world out there, and you can never be too prepared. Keychain knives are useful because they’re the last thing that an assailant would ever expect. Apart from being great in a pinch, especially if you’re in the carport late at night and you want to remain anonymous in your defensive techniques, it’s a great multitool.
One thing that most of us have on ourselves at all times are our keys. Unless you’re home and your ring is hanging on the hook, your keys are somewhere on you, whether it’s hanging from your belt or in your back pocket. When is it not useful to have a knife on you?

- When you’re out on the jobsite and your hands get disgusting, use your keychain knife to pick the gunk out of under your nails.
- File down your nails. It’s not as easy as using a nail file, but when you can feel them getting a bit too long and you have nothing but time to kill, do as the Romans do.

Keep Your Keychain Knife Maintained
Nothing is better than having a useful tool in a pinch, but nothing is worse than having that tool crap out on you. It’s all about how you maintain it. If you take a few steps to keep your knife sharp and useful, you’ll always be able to rely on it when you need to.
Oil – You should always oil your knife appropriately. Don’t saturate the thing, but do keep it oiled and return to this at least once every three months.
Sharpen – A dull knife is no good. Whether it’s for a hunting knife or not, it has to be sharp. It’s kind of the whole point. Sharpen this baby at least once every six months. If you find yourself using it on a frequent basis for household things, then sharpen it once every three months.
Cleaning – One of the biggest problems that users have with a pocket knife or keyring knife, is that it jams up or becomes hard to use. That’s because they’re not cleaning it. Oiling your knife is only so good; the knife has to be clean first.
