on glaziers and wood chisels, the metal portion of the chisel estending from the blade On ripping and fluoriflg/eIe.trichans chisebi. tiw straight portion of the chisel between the ch.imfrr and the taper.
charnfrr: the angled flat surface or equivalent radius betiswn the struck law and the body of the chisel encirding the perimeter of the struck face.
