  • Patent number: 4821418
    Abstract: This invention comprises a blade holder comprising a handle, shaft and clamp whose clamp is made in the shape of a U-shaped channel of a width to receive and retain a two-edged blade, and whose shaft is bent at an angle sufficient to assure that the centerline of the handle does not align with the centerline of the portion of the shaft that is attached to the clamp. By this configuration, both edges of the two-edged blade can be used in positions in which those edges could not have been conveniently used.
