  A metal boarding axe is a craftable item in the Forging society under the Weaponsmithing crafting discipline.  This is considered to be a difficult piece to make, though knowledge of the Expert Swappable Weapon Design technique will be beneficial to the crafter.

  This item is listed as a "finished metal swappable bladed weapon" ingredient type and is created using a forging hammer, some tongs, some metalworking oil, a grindstone and a metal anvil with forge.  A crafter may also find it helpful to have a shovel and a bellows on hand.

 A list of ingredients is provided:

   (1) refined metal ingot (10 volume)
   (1) finished wooden haft
