Abstract: A system for sharpening circular, knife edged blades operates to bias an infeed grinding wheel into contact with the first edge of the blade and an outfeed grinding wheel into contact with the second edge of the blade. The grinding wheels are spaced so that they contact the respective edges of the blade at a point which is spaced by no more than 1 inch from the center line of the blade. Contact between the grinding wheels and the blade is accomplished solely by pushing the wheels from their sides which are opposite the blade contacting surface. The system includes provisions for adjusting the position of the wheels relative to the blade so as to accommodate blade wear.
