ABSTRACT:
A sharpening tool has a flat central portion circular plate to which is affixed circumferential abrasive bead having convex profile and formed of an abrasive grit bonded by epoxy to the plate. The tool is less wide than the spacing between the depth gauge and the cutting tooth of a chain saw blade and is mounted to a motor which is pivotal on a frame to bring the sharpening tool into position between the depth gauge and the cutting tool. The sharpening tool may then be urged against the cutting tooth to cut a desired tooth profile.
