Forged Geologist's Pick

A geologist's pick of about 2½ pounds, with a square striking head on one side of the eye and a long curved point on the other, forged from 1¼ × 1¾-inch tool steel. After the eye is punched, the bar is cut part way through beside it with a hot chisel and the waste cut away, then each end is drawn out, under a power hammer in the original. The point is hardened like a cold chisel and tempered to dark blue; the head is then hardened about 2 inches back and tempered to brown or dark straw, with damp coal round the point so it is not softened again.
