Fire hardening is the process of removing moisture from wood, changing its structure and material properties, by charring it over or directly in a fire or a bed of coals. This has been thought to make a point, like that of a spear or arrow, or an edge, like that of a knife or axe, more durable and efficient for its use as a tool or weapon.
