Abstract: The tool is electrically heated and has a flat working surface, essentially horseshoe shaped. The working surface is heated to between 500.degree. F. and 900.degree. F. and pressed for from 3 to 10 seconds against the ground contact surface of a horse's hoof prepared for shoeing. The contact sears the insensitive part of the hoof, the horn, to dry out the horn, seal off the capillary tubes in the tubular of the hoof and flatten any irregularities left on the surface during the preparation for shoeing. This treatment reduces the potential for hoof damage caused by moisture. The working surface is on the horseshoe shaped part which encloses an electrical heating element. The heating element is attached to a handle for the tool. In the steady state heated condition the heat radiated by the tool equals the heat produced by the heating element and no thermostatic temperature control is required.
