Abstract
The device for sharpening a cutting blade presenting a sharp edge includes at least one grinding wheel provided at least on the surface with abrasive material. The grinding wheel has a cylindrical body presenting a V-sectioned peripheral groove, and is mounted to rotate freely about an axis contained in a plane generally parallel to the sharp edge of the blade and perpendicular to the median plane of the blade, with the axis being inclined by a predetermined angle with respect to the normal to the median plane of the blade. The sharpening device is further constructed to place the blade and the grinding wheel in contact and to provide for relative displacement of the blade and the grinding wheel in a direction parallel to the sharp edge of the blade.
