The sandwich's name is said to have come from the horseshoe-shaped ham slice initially used. The fries represented the nails, and the sizzling platter on which it was served symbolized the hot anvil.

Gates' buns and fries were the best. The sandwich had more of a fattier ham-style pork than the other chains. It was served on a round bun, which became my favorite because of its fluffy texture.
