摘要： A blade is advanced by controlled increments and brought against first one and then the other of a pair of grinding wheels which are specially configured to impart an improved cutting edge configuration on the blade. The cutting wheel consists of a convexly shaped grinding surface formed annularly on the outer periphery of the grinding wheel midway between the sides of the grinding wheel and terminating in convex valleys with additional convex grinding surfaces along the opposite edges of the grinding wheel. This profile of the grinding wheel imparts a cutting edge to the blade which is capable of greater number of honings before it loses its effectiveness. The apparatus for grinding this improved edge on the blade consists of a pair of coordinated clamping means which at all times holds the blade in clamped condition, first advancing the blade and then moving it laterally first against one and then against the other of the grinding wheels to impart the preferred cutting edge. The grinding action occurs progressively until the blade is completely ground at which time the blade is removed and the cutting wheels are redressed to the desired configuration profile.
