To sneak up on someone, you need to be silent and quick like a ninja. But to be truly undetected, you must also be prepared. You can't very well unscrew the vents to climb through the ductwork of a highly-secured facility if you've forgotten your screwdriver, for example. But that's where this tiny multi-tool comes in handy.
The credit-card-sized, black and grey steel multi-tool hides in your wallet, but when it's needed it will suddenly be revealed, and can perform one of its 18 useful functions: whether that be opening a bottle or can, slicing open a box, or functioning as a screwdriver, hex wrench, or ruler.
