The grinding disc includes an opening centrally located therein, with the perimeter of the opening forming a plurality of teeth projecting toward the center of the disc. The teeth are separated by generally horseshoe-shaped notches. The grinding disc further includes a plurality of groups of channels on one face thereof defining grinding ridges therebetween and extending from near the periphery of the disc inwardly to the opening in the disc. Certain of the channels in each group intersect with certain other channels in at least one other group to form a cross-hatching of channels.
