From Wikipedia: "A screwdriver is a tool for driving screws and often rotating other machine elements with the mating drive system. The screwdriver is made up of a head or tip, which engages with a screw, a mechanism to apply torque by rotating the tip, and some way to position and support the screwdriver."

This was a quick model made in just a few minutes, based on one from my own toolbox (although mine is a Phillips).  It has a transparent plastic handle and a steel shaft.  This prop has 168 polygons, mostly quads.  The textures are packed in the blend file.
