Edwin W. Foster, Elementary woodworking (1903)
“ Two classes of chisels are in common use: the framing chisel used for heavy work, such as the frames of buildings; and the firmer chisel. The framing chisel is strong and heavy, and has a handle capable of withstanding the blows of a mallet. The firmer chisel is designed for finer and lighter work without the mallet. Fig. 30. The Framing Chisel Fig. 31. The Firmer Chisel Fig. 32. Proper Position for Horizontal ChiselingThe chisel must be sharp if we wish to do good and accurate work, and a cut on the hand made by such a sharp tool is liable to be a deep one. ”
