This removal driver is made with a patented technology in which the multi-faceted
extension of the screwdriver that engages with the screw socket expands in the outer
diameter direction when the handle is rotated counterclockwise.
As the gap between the screw socket and the screwdriver end is eliminated
by the expansion of the multi-angle extension, the force of friction increases,
preventing damage to the screw socket.
Moreover, by turning the handle counterclockwise, this screwdriver can easily remove
screws that have already been damaged and cannot be removed by a conventional
screwdriver.
