  • Razor blade sharpener
    Patent number: 3979857
    Abstract: A case is formed by a rectangular base and a rectangular lid that is hingedly attached to the base. Flush with the top surface of the base is an abrasive disc that can be rotated by a knob underneath the base. A double-edged razor blade can be put into a recess in the lid. A strip of flexible material bears against a razor blade so placed when the lid and base are closed together. The recess in the lid and the strip cooperate to urge one side of one edge of the blade against the disc when the lid and base are closed. The knob may then be turned to sharpen the blade.
