Abstract
A sharpening system is formed of a plurality of spaced, elongated, cylindrical sharpening rods formed of aluminum oxide embedded in ceramic. The rods are positioned in an open framework in parallel relationship. The rods are held at opposite ends by polygonal plates with the rods being supported at the apices of the polygons. A tightening rod is provided which holds the plates together and which permits the sharpening rods to be fixed in position or loosened for rotation when necessary.
