The wrench is custom stamped and used to remove threaded tools that self-tighten during use. The three-way design works with various wrench flats: 1/4" hex Screwdriver Bits, 5/16" hex TightFitŪ threaded shank drill bits and Extensions, and 7/16" hex Collets, etc. It is black oxided to prevent corrosion while enhancing appearance.
