The 18-Tool Credit Card

It's a pocket rocket and it's here to make your life a whole lot easier.

This fantastic flat multi-tool is the size of a credit card, yet contains an incredible 18 integrated tools.

The Wallet Ninja, created by Vante Toys, operates as a can-opener, box cutter, letter opener, phone stand and fruit peeler, as well as incorporating six wrenches and four screwdrivers. The Ninja is made from 4x heat-treated stainless steel, so it's built to last, and it's available for just £9.94 from Amazon.

It's probably more useful than a real ninja; you can't get too much fruit-peeling accuracy with a sword.
