The grinding surface of a grinding stone is formed from a circular conical surface, a drive device for rotation is installed within a housing. The blade of a cutting tool is ground while the longitudinal direction of the cutting tool is aligned with the direction of a generating line of the grinding surface. When grinding the blade, the cutting tool can be aligned with the direction of the generating line of the grinding surface and the blade can be brought in contact with the grinding surface without the handle of the cutting tool and the hand that holds the cutting tool being interfered with the grinder. This is achieved irrespective of in which one of the directions of lines the tip of the blade faces, the lines being obtained by extending the generating line of the grinding surface from both ends of the generating line. |
