  • Patent number: 4628642
    Abstract: A knife sharpening device has a slide (8) which carries freely rotatable grinding wheels or disks (11, 12). The slide is adjustable along a bar (5) of a frame (1, 2). The slide is fixed against lateral displacement in an adjusted operating or rather grinding position by the engagement of a pin (17) with a toothed rack (6). The grinding disk or disks are preferably driven by the positive rotation of the knives being sharpened. A slight vertical movement of the grinding disks is possible due to a respective play in the vertical direction.
