Abstract
The method is for sharpening a blade. An automatic sharpening apparatus is provided that has a housing with an elongate opening defined therein. A blade is placed inside the elongate opening. The blade is tightened between self-centered clamp holders. The rotation of the grinding wheel is turned on. The rotating grinding-wheel engages an underside of the blade and automatically moves along the blade by following a contour of the blade. While the grinding wheel moves along the blade, a counter-weight provides a counter-weight to the grinding wheel. The blade is sharpened while the blade is stationary inside the elongate opening of the housing.
