This photo shows two latches after receiving their hot finish. The finish is wiped off after they are cool. The latch to the left is a bean style. The latch to the right is the heart style.

Two finished latches are shown after having the final paste wax. The latch on the left is a heart latch for an exterior door, the one on the right for an interior door. The latch on the left doesn’t have a forged slot like the one on the right. Instead a slot is cut through the metal of the cusp. The thumber is held in place in a different fashion.
