Forged Ball-Peen Hammer
A 2-pound ball-peen hammer forged from 1½-inch square tool steel; a 6½-inch bar gives two heads. The eye is punched and drifted, the body fullered and rounded so it tapers both ways from a thick centre, then the face is drawn out and swaged and the ball peen rounded in a bottom swage. Both ends are hardened by dipping them in turn, with water dripping on the face, and tempered from the heat held around the eye: dark brown for the face, brown or purple for the peen. The eye cools last, which keeps it tough.

Lower about 1½ inches of the face into water, then harden the peen the same way while water drips on the face, keeping the eye hot. Polish the ends; take the face to dark brown and the peen to brown or purple, then dip the ends alternately so the eye cools slowly.
