Iain Sinclair's CardSharp Credit Card Folding Safety Knife isn't your run-of-the-mill pocket knife. It isn't even one of Victorinox's 100-in-one-do-it-all Handyman knives. The CardSharp is a svelte knife that's insanely thin and folds into a card to fit in your wallet.
At .078-inches thick and weighing only 13 grams, the CardSharp is just slightly over double the thickness of a standard credit card (.029-inches). The knife's 3-inch blade is made of stainless steel, so no rusting here folks.
When folded, the CardSharp's "sheath" cannot be accidentally opened. Phew, it's reassuring to know that we won't unintentionally slash our pants or something while carrying this pocket knife around.
The CardSharp is relatively cheap too. It isn't officially on sale yet, it'll start shipping in January for about $23 and can be pre-ordered.
