If you've ever felt the urge to feel more like James Bond, then you need the Iain Sinclair 'CardSharp.' An amazingly sharp knife disguised as a card, this wicked tool can be folded up for easy carrying.
Perhaps you're not one of those individuals who enjoys that extra "bulk" in your pants; the Iain Sinclair 'CardSharp' is perfect for those purposes. Simply slip it into your wallet for carrying convenience. Though I don't know why anyone would want to disguise a knife, but if you're going for incognito, this is just for you.
