Ian Sinclair Credit Card Knifeeatures include a child-proof safety lock? polypropylene body & stainless steel blade. Just three ingenious folding operations turn the card into an elegant pocket utility tool. Less bulky than a pocket knife and as sharp as a scalpel. Cardsharp is the first real innovation in penknives since the first folding knife? which has been around for over 2000 years and is virtually unchanged from today's Swiss Army penknife. Cardsharp is thinner? lighter and due to its use of surgical steel: sharper. Cardsharp was originally designed as a lightweight surgical knife that can be easily transported and safely disposed of by hospitals and medical centers together with paramedics and aid workers throughout the world (without needing expensive and wasteful sharps containers).
