Forged Cross-Peen Hammer

Smiths make their own hammers. A bar of high-carbon steel is punched through hot for the eye, the eye is opened to shape with a drift, one end is drawn into a peen, and the head is cut off the bar. It is hardened all over, then tempered by heat run from the middle: the eye and cheeks are left soft (blue) so they do not crack, the faces harder (straw) so they do not dent. The handle is riven ash or hickory, wedged into the eye.

Punch the eye

At a yellow heat, drive the hot punch halfway in from one side, turn the bar over and punch through from the other side over the anvil's hole. Cool the punch often.

Drift the eye

Drive the drift through the hot eye from both sides to open it to the handle's shape.

所需工具：

Draw the peen

Mark the head's length. Draw one side of the eye into a wedge-shaped peen with the fuller and flatter, its edge across the handle's line.

所需工具：

压槽铁（fuller）

平锤垫铁

Cut off and dress

Cut the head off the bar on the hot-cut hardy. Square and slightly dome the face; round the peen's edge.

Normalise

Heat it to a red heat and let it cool in still air, three times, to relieve the forging.

所需工具：

铁匠炉

Harden

Heat evenly until a magnet no longer sticks, and quench it in warm oil in a lidded bucket, moving it, for a few minutes.

Temper from the eye

Sand the faces bright. Heat the middle of the head with the torch and watch the colours run out toward the ends: when the faces reach straw and the eye is blue, quench it in water.

所需工具：

砂纸

丙烷喷灯

Handle

Shave the handle stock to fit the eye tightly, drive the head on, saw a kerf in the handle's top and drive a glued hardwood wedge into it. Trim flush and oil the handle.
