Patent abstract
A screwdriver element includes two bits, each with a sinuous distal tip end and a screw element includes a head having an X-shaped slot that has sinuous side walls. The bit distal tips have a left-handed shape and a right-handed shape and the side walls of the screw element head are curved in a corresponding manner whereby twisting the screwdriver after the tip is engaged with the screw head slot will cause the screw driver tip to be drawn into tight engagement with the screw head.
