Wetterlings states that all their axe heads are hardened and tempered. Are quality axes like GB ,Wetterlings and Ox-head hardened at all around the eye and poll area? Is the eye just left in a completely soft annealed state? I always thought the eye area was partially hardened although not nearly as much as the edge. If you protected the edge by burying it in wet dirt and then burn out an axe handle would not that weaken the eye of an axe?
