Your wallet just became infinitely awesomer

The CardSharp is just about the most useful and convenient item we've come across lately.

A knife is a must-have for the prepared adult (unless you've somehow evolved fingernails that are as sharp as steel), but not everyone wants to carry a separate knife or add more bulk to their already rotund keyring. Well, here comes CardSharp to the rescue!

The CardSharp folds down to the size of a credit card, giving you an effective, high-quality, and impressive tool wherever you go.

Always have a knife at the ready

If the Boy Scouts taught us one thing, it's that adults shouldn't wear a uniform designed for boys. If they taught us anything else, it's to always be prepared. Thanks to the CardSharp, you're one step closer to perpetual preparedness.

And even though it folds down to the size of a credit card, the CardSharp is perfectly balanced and features a sturdy handle.

A serious blade for serious situations

The CardSharp's blade is made from surgical steel, which is known for its strength, ability to maintain a cutting edge, and corrosion-resistance.

Recently, an independent testing laboratory, CATRA, awarded the Cardsharp VERY GOOD status for sharpness and life.

Guaranteed to fold and unfold for a lifetime

The polypropylene sheath of the CardSharp is guaranteed to withstand a lifetime of folding and unfolding.

The material make-up is such that it can be rotated through 180 degrees without any degradation whatsoever. So, bust this baby out and show it off to your friends. The CardSharp can handle an infinite number of folds.

Not a pain in the wallet... literally and figuratively

The CardSharp is engineered to a thickness of only 2.2mm and weighs only 13 grams. Most conventional pocket knives are orders of magnitude thicker and heavier. You can keep the CardSharp in your wallet and you won't even know it's there — until you need it!

Additionally, the CardSharp is affordably priced so that you'll still have something to carry around in your wallet after you've bought one (or six).

Super-safe when not in use

The CardSharp features a variety of clever safety features.

When closed properly (safety catch turned to reveal the green circle), the blade is closed such that it cannot accidentally cut or blunt. When opened, the blade will be locked (avoiding the blade tremors of low-quality pocket knives) and will not close accidentally.

Finally, it's impossible to lose the CardSharp's sheath because the knife and the sheath are integrated as one piece. Yep, the guys who designed the CardSharp are wicked smart.

Frequently Asked Questions

Question: Is it waterproof?

Answer: Yes! The CardSharp is absent of any hinged parts that can rust. You can even toss this thing in the washing machine without fear of corrosion.

Question: What are the legal implications of owning this type of knife?

Answer: Because the blade is under 3" long, most states do not consider it a concealed or deadly weapon. However, we are not legal authorities. You would need to consult your local statutes for specifics. That being said, we've yet to find a law that has a problem with a knife with a blade under three inches long.
