The Cardsharp Credit Card Knife [$9.97] has 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 420 series surgical stainless steel: sharper. Sharp enough in fact, that it can cut through an automobile safety belt in an emergency.
