ABSTRACT:
A method for manufacturing cutting knives, in particular granulator knives in which a mass of highly wear resistant material is bonded along one edge of a main body of a tougher, more ductile material, the cutting edge machined into the mass of wear resistant material, to increase the service life of the knife between sharpenings without subjecting the tool to breakage during heavy use in a granulator.
