Abstract
A blade sharpening method and apparatus is characterized by sharpening the blade in a single station grinding assembly. The grinding assembly includes two opposed abrading wheels which interlock to form a nip for sharpening the blade. The wheels each include a first coarse portion for roughing an edge of the blade, a second fine portion for finishing the hone facet, and a third coarse portion for forming other facets adjacent to the hone facet. The wheels are specially contoured and have parallel axes tilted relative to the direction of travel of the blade. The striations formed on the facets of the blade by the abrading wheels extend at the same angle in both facets.
