  • Sharpener for commodity slicing machine
    Patent number: 3958478
    Abstract: The guard cover for a commodity slicing machine sharpener extends over and protects the otherwise exposed knife edge at the knife sharpening area. The guard protects the knife edge at all times regardless of whether the sharpener is in the sharpening position, storage position, or is being moved between these positions. The sharpener employs a non-rotatable honing stone which seeks proper honing relationship with the knife upon coming into contact therewith.
