One crafting Blacksmiths' selection in the Axes category is the Double Axe. It can be used to return House Addons to their deeded form and on corpses to produce feathers, hides, raw birds, raw ribs, scales, and wool.
The Double Axe requires a skill of 29.3 to create and consumes 12 ingots in the process. The axe may hold its maker's mark and retains the color of the material from which it is made. Crafted versions can have their durability increased, via Powder of Fortifying, to a maximum of 255 and dyed with Pigments of Tokuno.
