One thing you would never find me without is my knife. I have several of them because you never really know when your going to need it. This cool invention has really taken a utility knife to a new level and I love it! CardSharp is a beautiful and innovative design for a utility knife. Although this looks sort of petty, it is super super sharp. It takes only 3 unfolds to turn this card into an elegant utility tool. It’s has an extra long stainless steel surgical blade to guarantee longer lasting rust free sharpness. Surgical Steel is the highest grade material you could make a blade out of and it stays sharp much longer! This knife is slimmer and lighter compared to your traditional knife, just slip it safely inside your wallet or kit bag. I would use this for camping and hunting. Props to this designer for coming up with such an amazing product design!
