Creditor Carbon Fiber Money Clip Knife

We're big fans of minimalistic wallets, but we're not sure we've ever seen one that doubles as a knife. Designed by John Kubasek, the Creditor Carbon Fiber Money Clip Knife ($200) is a cunning combination of materials and functionality, featuring a carbon fiber and titanium body that folds to become credit card size — hence the name — while a clip holds your cash and cards, but press down on the side of the handle and it unlocks to become a handy six-inch blade. It can even fit into another wallet with the clip removed. Just be careful not to inadvertently cut your money in half — nothing says "shady" like paying for your Starbucks with a taped-together twenty.
