A Folding Safety Knife for Your Wallet

To be honest, we’re not exactly sure of the purpose of this nifty device (to stab unsuspecting pickpockets with?), but it still looks pretty cool nonetheless. The Cardsharp Credit Card Folding Safety Knife is basically just what it sounds like: a knife in the shape of a credit card.

Except, it’s not actually a credit card and doesn’t hold one, so it seems to be only good for fitting into your wallet. We guess that’s a cool place to hold it, and it certainly makes it easy to take with you wherever you might go. You might have a tough time getting it through TSA, though.

It’s made with ultra-light aluminum and an anodized surface, so this thing’s pretty durable, and it locks into place so you don’t have to worry about it popping out and poking you in the thigh. Iain Sinclair, the company that designed the knife, claims it’s great for outdoor use when camping or even for cutting through safety belts in a car in an emergency.

It was originally designed as a surgical knife so it’s pretty sharp, and the blade is 65mm long. It could certainly come in handy in a pinch, but we don’t actually recommend trying to use it for self-defense.

There are multiple models of the knife on the website, though you’ll have to check back regularly to see when it becomes available again; it’s currently in pre-order for the newest one.
