Cardsharp 2

Do you favour preparedness (in the form of a knife) but lack pockets to spare? Iain Sinclair’s impossibly thin and light Cardsharp 2 takes up but a card slot in your wallet, yet contorts to reveal a 3 inch surgical stainless steel blade that’s legal virtually everywhere. We wouldn’t recommend hunting with a Cardsharp, but one thing’s certain: this knife’s bound to be with you when you need it (hopefully limited to opening letters).

Get it here – 15$.
