This system involves the use of a 3/8 drill
as the power source, an articulated clamp
 to hold the drill, a perforated diamond
 coated disc which enables the operator
 to actually see through the disc and
 observe the material as it is being
removed to afford maximum control, and
two fiber wheels for finish honing and
 polishing.  Everything needed to do
effective power sharpening is included
except for the drill.
