  • Patent number: 5007483
    Abstract: The present invention is a buffing kit for use by farriers to impart a high gloss to the hooves of horses and other hooved animals, in competitions and exhibitions. It consists of several rectangular blocks of resilient material having replaceable sheets of abrasive material on the two major faces. The blocks should not be deteriorated by water and soap, and are sized to be easily hand-held. The abrasive material ranges from approximately 100 grade to 3600 grade. In use, the farrier wets the abrasive surface and, starting with the coarsest grade, removes the major roughnesses by a buffing procedure. Progressively finer grades are used in turn to obtain the desired finish. Preferably, the two finest grades do not differ from one another substantially. Worn-out sheets are replaced by fresh. Three blocks, with a total of six major surfaces, provide a satisfactory progression in abrasive grades to obtain almost any desired gloss, and will service about five horses.
