This screwdriver concept is adaptable so that one device can change to suit the size requirement of different screws.
Called the 'Push Driver' and designed by Wan Ki Kim, this screwdriver has a modern outward appearance and highly functional design. The tool is made for Phillips head screws in any size and has a design that is tapered. When the size of the screw head is small, users can put the screw on the third setting and retract it to make it bigger if necessary. The tool works when the user presses on the driver -- just like the way that one would a retractable pen or pencil.
This screwdriver concept would make the work of designers, creators and construction workers much more simple.
