Credit Card Foldable Knife – 2.75-Inch Blade, Wallet-Sized, Blade Lock Safety, Ultra-Thin Disguised Design, Black

The Blade You Forget You’re Carrying

Here’s the deal — this isn’t trying to be your main knife. It’s not replacing the folder in your pocket. What it is, is a blade that lives in your wallet and weighs basically nothing. You pull it out, unfold it, and you’ve got a 2.75-inch knife with a blade lock. It’s for those moments when you need to cut something and your real knife is at home on the counter.

Who This Knife Is For

This is for the person who likes having a backup plan. You forgot your knife today but your wallet’s always with you. You want something to open packages when you’re at someone else’s house. You’re the kind of person who appreciates a clever tool. It’s also a popular gift item — people love the “credit card that turns into a knife” factor. At five bucks, it’s practically an impulse buy.

Clever Design, Honest Limitations

The knife folds from a flat, credit-card-sized shape into a working blade with a handle. The blade lock keeps things secure when it’s deployed — you’re not going to have the blade fold on your fingers mid-cut. At 2.75 inches, the blade handles light cutting tasks like opening packages, cutting tape, slicing cord, or breaking down boxes. It’s sharp out of the package.

What it’s not is a heavy-duty tool. The handle is thin because it has to be — the whole point is that it fits flat in a wallet. You’re not going to carve wood with this or use it for anything that requires serious grip pressure. But for quick, light cutting tasks? It’s surprisingly capable for something that literally fits behind your credit cards.

Practical Details

Dimensions are 3.38 by 2.13 inches when folded — standard credit card size. Thickness is just 0.13 inches. Weight is 0.1 lbs. The whole thing is black and looks like nothing special sitting in your wallet. The blade lock engages with a click when you unfold it. It’s a simple mechanism that works. Check local knife regulations before carrying — some jurisdictions have rules about concealed blades.

Five bucks, fits in your wallet, actually useful — add one to your cart just because.
