There are a few weapons created by the people of Arrea. They are generally specialized forms of existing weapons.

Great Hammer- The dwarven great hammer is a mighty weapon created by the priesthood of Moradin.  It is basically a small block of steel on top of a mighty shaft, typically wood. It is basically a maul. A priest of Moradin with the War domain can use the great hammer as a martial weapon.

Mauler: A mauler is a great crossbow created solely for damage potential.  The mauler fires two bolts per shot, both bolts get a to-hit roll at -5, but they must be firing at the same target.  If both bolts hit a man-sized target or smaller, the target must roll a Reflex save (DC = damage dealt) or be knocked prone. When fired a mauler needs to be held in two hands and even in two hands it is difficult to aim properly (all attacks are -5). The best way to fire a mauler is with a stand to hold it up and allow you to aim it (this makes the attacks -2). The mauler is a dwarven weapon.
