Abstract

The invention relates to a device for sharpening cutters or similar objects, having a plurality of sharpening points arranged in succession in the direction in which the cutter or similar object is drawn. To increase the sharpening efficiency, minimum roughness of the blade facets being achieved despite a high degree of material abrasion, the invention proposes that the sharpening points (4, 4') of steel arranged upstream in the direction of drawing should be followed by sharpening points (3, 3') made of ceramic material. <IMAGE>
