Here are some of the steps involved in forging a Proper Viking Axe, with a forge welded bit, tapered eye, and correct shape. It would have been used for everything, but is set up to excel at carpentry work as well - with the offset bit and non symmetrical edge bevel. It starts out as 1" square A36, about 4" long. The one side then gets "upset" to build up the material for the front portion of the axe, and the rear section stays about 1" square for the eye. Next the hole that will become the eye is hot punched slowly with hand hammers. After the eye is punched, it is drifted out about 75% of its final size. The edge is hot cut, beveled, opened and cleaned to accept the high carbon steel bit, which will then be forged to shape, and forge welded into the axe head. Here you can see the type of fire that is necessary to forge weld the bit into the axe head.
