Blade

The blade has different lengths and shapes depending on the application and tradition. It should be as thin as possible, for the least possible penetration resistance, maximum bending for relief of the cutting edge (hardening +80 mm) the sides parallel for a constant short resharpening. It can also be hollow ground. The thickness should be 5 mm or better less, which it can withstand. The axe heel-axe toe-end of the handle should be in line, for as little vibration as possible, but this depends on the correct angle of impact. The shape of the blade can also be that of a German carpenter's axe, for limbing the trunk.
