Tool Tank looks like a toy tank keychain that does nothing more than make a bunch of keychain look less boring, but it is in fact a mini screwdriver that is capable of performing tasks like tightening and loosening screws for various purposes such as repairing and maintaining stuff around the house.
The clever design puts the parts of a multi-bit screwdriver in the shape of the tank. The tank’s turret is obviously the most important part, not only in a real tank but also for this keychain tool. It holds the screw bits magnetically in place while the turret moves vertically up and down freely across a 90-degree angle to suit the task at hand. You may play physics games with it in your hand.
As for the tracks of the tank, the metallic parts of the wheels are actually different-sized screw bits cleverly held in place magnetically to complete the look of a miniature toy tank.
One cool-looking keychain that comes with a useful function. The Tool Tank is due for a February 2012 release and retails for £9.99 from Spinning Hat.
