Stone Carving Chisels: Mallet-Headed Plain and Tooth Chisels and Points for Soft Stone (Holford, 1907)

Soft stone such as limestone and sandstone is cut with chisels struck by a wooden mallet, so their heads are broad and a little rounded. H. Holford's 20th Century Toolsmith and Steelworker (1907) shows a set: plain chisels, tooth chisels with a row of sharp teeth, and points, forged from 3/4 inch octagon steel of 75 points carbon and tempered a very pale blue. He gives no lengths, widths or tooth spacing; those are unknown here. The brine bath is from his chapter on the hardening bath. Source: H. Holford (1907), pp. 21, 131-133, 140-141.
