Abstract
A generally rectangular three dimensional body is provided constructed of two superimposed layers of abrasive material. The layers of abrasive material have different abrasive properties and the body is provided with three parallel bores extending through the two layers of the body and spaced longitudinally therealong. The bores are approximately 1/8 inch, 7/8 inch and 3/4 inch in diameter and the opposite ends of the bores open through parallel planar remote surfaces of the two layers of the body and are provided with inwardly tapering conical counterbores. The body of abrasive material may therefore be utilized to sharpen the beveled ends of cylindrical cutting members such as dehorners utilized to dehorn calves at branding time.
Claims2
A sharpening stone for sharpening dehorners, said stone comprising an elongated body defined by a pair of elongated superposed plies of rigid abrasive materials graded as fine and coarse abrasives, the remote surfaces of said plies being substantially planar and parallel, said body having a plurality of longitudinally spaced bores of different diameters formed therethrough with the opposite ends of said bores opening through said remote surfaces, said opposite ends of said bores including inwardly tapering counterbores.
