ABSTRACT:
A method of sharpening cutting blades of the type made from bar stock type material, the method comprising producing relief surfaces on the cutting profile surface. The method comprises forming first and second relief surfaces on the cutting profile surface. The first relief surface extends from a location inward of the cutting edge to the back face and is oriented at a first relief angle with respect to a side surface. The second relief surface extends from the cutting edge to the first relief surface and is oriented at a second relief angle with respect to the side surface with the second relief angle being smaller than the first relief angle. The cutting blades may comprise a uniform cross-section and the cutting profile may include a protuberant portion adjacent the top surface of the cutting blades.
