  • Apparatus and method for sharpening blades at a predetermined angle
    Patent number: 6761623
    Abstract: A method and apparatus for the sharpening of blades, particularly the blades of a lawnmower are provided. In the present invention, a blade sharpening apparatus with a supporting base comprises a blade retention and positioning mechanism, a blade sharpening mechanism and a guide rod for directing the blade sharpening mechanism laterally across the width of the apparatus. In a preferred embodiment of the present invention, the blade retention and positioning mechanism includes a hand operated crank for rotating the blade support means. Rotation of the blade support means allows for the proper positioning of the blade with respect to the sharpening mechanism so as to generate the correct sharpening angle for the sharpening of the blade. In such embodiment, the sharpening mechanism may be a lightweight, portable grinder mounted onto a supporting plate for movement along and rotation about a guide rod mounted to said supporting base of the apparatus.
