  • Patent number: 5694660
    Abstract: In accordance with the present invention, a tool for cleaning shoe soles having cleats comprises a thin, elongated bar of material wherein at least one end comprises a generally V-shaped notch portion and, on at least one side of the notch portion, a scraping portion to facilitate the removal of mud. The notch portion is formed by converging surfaces having a relatively wide open end tapering to a relatively narrow closed end. In use, the notched portion is pushed into a cleat, which it contacts at two points, and rotated around the cleat, causing a scraping portion to clean around the cleat periphery. Advantageously the notch portion has a width greater than its depth to permit cleaning of a wide range of cleat diameters, and the notch walls are straight (rather than beveled) to provide solid pivot contacts. The scraping portion is advantageously beveled.
