    摘要： A sharpening system for a meat grinder is provided. The sharpening system embodies two types of sharpening stones for sharpening the cutting edges of the knife blade and the hole plate, respectively, of the meat grinder, wherein each type of sharpening stone operatively associates to the drive arbor of the meat grinder. By interchangeably replacing the knife blade along the drive arbor with one type of sharpening stone so as to sharpen and resurface the hole plate, or replacing the hole plate along the drive with the other type of sharpening stone to sharpen and resurface the knife blade, the present invention provides hands-free sharpening with no additional machines or tools.
