Every Dwarf Warrior is trained in the use of an axe. Even though who eventually choose the route of gunpowder or crossbow have an ability to hack at their foes with a hand-axe or two.
For those wealthy enough to afford it, they can take their axe to the runesmith of the clan who, for a price, will inscribe runic symbols which increase the potency of said weapon.
For Short-arse, her runic axe seems to have but one rune upon it: the Master rune of tripping over her beard. Therefore this weapon is currently unused, lying dormant in her backpack until she can figure out a way to avoid such ignominy in future.
