Folding utility knife that fits in your wallet

The CardSharp 2 from Iain Sinclair is a folding utility knife that turns into a credit-card object when it's not in use, suitable for storing in your wallet. It's a clever little design, unlike a lot of credit-card tools that leave you with a rectangle of plastic in one hand and a tool in the other, the "card" folds around to become the handle.
