Abstract: Method and apparatus for sharpening a cutting tool. In some embodiments, an abrasive endless belt is rotated in tension along a neutral plane between spaced apart first and second rollers. A guide assembly has spaced apart first and second guide surfaces which collectively converge to an intervening base surface to form a guide channel. Upon insertion of a blade of a cutting tool into the guide channel, a selected side of the blade contactingly slides against at least a selected one of the first or second guide surfaces and a first portion of a cutting edge of the blade contactingly engages the base surface to serve as a plunge depth limit stop for the blade. The endless belt is contactingly deflected by a second portion of the cutting edge away from the neutral plane to sharpen the second portion while the first portion remains in contact with the base surface.

Abstract: A method to make sawing beads by means of laser cladding is disclosed whereby metal matrix powder is molten by means of a laser beam on a rotating sleeve while diamonds are thrown in the molten metal pool. By carefully controlling the temperature of the molten metal pool at or above 1150° C. for less than 200 ms the internal graphitization of the diamonds can be limited. Although some of the diamonds in the sawing bead show internal graphitization it is demonstrated by the inventors that a sawing cord using the bead obtained by the method has an above standard sawing performance.
