- A. substantially rectangular, elongate base member havng side ends and forward and rearward ends, said base member defining plural grooves transversely of the side ends thereof, each said groove being set parallel to the other, discrete distances in depth, relative to the forward and rearward ends of the base member;
- said grooves in vertical cross-section defining a declining front wall from the forward-most portion thereof to the bottom and a substantially vertically extending rearward wall the topmost of which is coplanar with the base member top defining a first abutment means for an abrasive sheet;
- B. a serrated, abrasive sheet cutter, contiguous the forward edge of the base member, said cutter projecting above the plane of the base member and being parallel to the said respective grooves thereof;
- C. a second abrasive sheet abutment on one side end and projecting above the plane of the base member, said second abutment being disposed normal to said first abutment means and said cutter and being coextensive with the forward and rearward ends thereof, whereby to confine with said grooves an abrasive worksheet on two sides thereof, a measured distance in depth from the cutter.
