Marietta A Maid of Venice After annealing the steel we score it diagonally with a hack saw, when it may be broken in triangular pieces in a vise. Hunting with the Bow and Arrow Proper annealing means the heating of the steel slowly and uniformly to the right temperature, the holding of the temperature for a given period and the gradual cooling to normal temperature.
