Abstract:
1. A tool for use in removing material from a workpiece to smooth a surface of the workpiece, said tool comprising: a shank portion and a working portion constructed of a rigid material; said shank portion adapted to be held in a non-flexible manner by a power-driven implement of the type providing movable contact between said tool and the workpiece; said working portion of said tool connected to said shank portion, said working portion adapted for contacting said workpiece, and said working portion having a surface area adapted for preventing abrasion of the workpiece when moved into contact therewith; and said working portion of said tool having one or more depressions formed in said surface area, each depression having an abrading mechanism for abrading raised areas of the workpiece, said abrading mechanism does not protrude above said surface area, whereby when the raised areas of the workpiece are abraded and reduced in height by the working portion of said tool, the surface area of said working portion of said tool is then caused to engage the workpiece and further abrasion of the workpiece is prevented.
