Japanese hatchet and axe heads are normally made with a 3-layer laminated steel head (Warikomi): there is a hard steel insert of carbon steel in the middle for the cutting edge and two softer iron laminations to support it and form the rest of the head. The forest hatchet and the splitting axe are made of unlaminated steel.
