Cardsharp3 by Iainsinclair new metal folding credit card knife. Featuring a straight, double edge blade of the sharpest grade surgical stainless steel.
Cardsharp3 is the sharpest knife in the world at the lowest cost.
The new simplified and improved three part construction incorporates a robust Zytel® child-proof safety lock built into the single piece Santoprene™ polypropylene body (living hinges guaranteed for life) giving the knife excellent rigidity in both open and closed positions.
Just three ingenious folding operations turn the card into an elegant pocket utility tool.
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).
