Cardsharp 4 Folding Knife

When you need the ultimate in knife concealment and portability, it’s tough to beat the Cardsharp 4 Folding Knife ($90).  Crafted from a wafer thin strip of ultralight aluminum with a 420 series surgical stainless steel blade, the Cardsharp 4’s 65mm cutting edge is as sharp as a scalpel, but the knife is as easy to carry as a credit card.  In this latest Cardsharp version, an inproved construction with a two-stage, child-proof Zytel safety lock helps prevents accidental opening and gives the knife improved rigidity, while a new Zytel rivet securing the blade adds to the Cardsharp 4’s robustness, making it suitable for a huge variety of cutting tasks.  And if you’re worried about the difficulty of transforming the Cardsharp 4 for use, don’t. The Cardsharp 4 changes from closed to open position through three simple folding operations, making using it a breeze.
