Despite the “tank” name, the Tool Tank is probably the cutest screwdriver ever. The turret of the tank fits one of three screwdriver heads, which store neatly in the tank treads when not in use. It all fits onto a keychain. The turret flips up so you can actually use the screw head of your choice. I don’t think you would want to do any major construction projects with this thing but the handiest tool is the tool you have on hand. Fire away- available starting next month for about $14.
