These photos show a simple one heat modification that can be used on a daily basis. All four blows take place on the horn. Remember to lock the shoe against the horn before each hit. This is an efficient way to turn generic or front patterns into a nice squared hind pattern with a minimum of effort. Notice that the shoe has been turned after the first hit and then again after the third hit. Your first two blows set the toe, the next two straighten the branches at the first two nail holes.
