Iain Sinclair‘s Cardsharp 2 is one of my favourite gadgets. It‘s a beautiful credit card sized folding knife. First of all, it has a very aesthetic design and is technically well considered. But I also like the fact that you only need a little slot in your wallet to take it discreetly with you. So it‘s ready for action at all times. You just need three easy folding operations to prepare a sandwich. Or a knife fight.
