Wood Chisels and Gouges Forged from Tool Steel
A woodworking chisel is a flat steel blade with a bevelled edge, hardened and tempered, on a wooden handle; bevelled sides let it into tight corners. A gouge is the same with a blade curved in section, for hollowing. Forge a set of widths from tool steel, harden them, temper to a dark straw and hone them sharp.

Draw tool-steel bar out flat to each blade width, taper it slightly toward the edge and forge a square tang on the other end. For gouges, set the hot blade over a round groove of the swage block and drive it in to curve it.
