The Wallet Ninja is one of the bestselling multi-tools in the world and for good reason. This nifty little gadget is the size of a credit card yet features nearly 20 different tools. In addition to the classic bottle opener, screwdriver, and ruler, the Wallet Ninja also features a nail puller, hex head nuts & bolts, cell phone stand, and fruit peeler.
