CardSharp is a beautiful and ingenious design of a utility knife. Don’t underestimate this knife, it might look like an ordinary knife, but in reality this is a supersharp utility knife. It takes only 3 folding operations to turn this card into an elegant utility tool. It’s been designed with extra long stainless steel surgical blade to guarantee longer lasting rust free sharpness. To prevent any injury or blunting, it has built-in protective sheath. This knife is slimmer and lighter compared to your traditional knife, just slip safely inside your wallet or kit bag. It’s a great tool for camping and hunting. Designer : Iain Sinclair [via] [Buy Here]
