The Iain Sinclair Cardsharp 4 Credit Card Knife has been designed to be the ideal knife for anyone. CNC machined from a wafer thin strip of ultralight aluminum, the Iain Sinclair Cardsharp4 Knife has ultimate robustness and strength. New construction with two-stage, child-proof Zytel safety lock helps prevent accidental opening and gives the knife excellent rigidity in both open and closed positions. The new improved Zytel on the rivet of the Iain Sinclair Cardsharp Knife secures the blade to the body. Spring-loaded Nitinol hinges ensure the Iain Sinclair Cardsharp4 remains flat while in card mode with no sagging.
