Ian Sinclair Design contacted us with news on the release of a new version of their Cardsharp, a popular credit card size pocket knife. Cardsharp4
is a new and improved version of the superlight and supersharp utility
knife. The card itself is now made from ultralight aluminum instead of
plastic used in previous versions. Other significant improvements are
the inclusion of a two-stage safety lock, a new Zytel rivet for securing
the blade to the body, and new spring-loaded Nitinol hinges to ensure
the Cardsharp4 remains flat while in card mode with no sagging. And yes,
it still fits neatly into your wallet, and still features the cool
origami style folding system. watch the video
