Norsun uses a mace-flail with a morningstar head and I've seen plenty of characters using hammers and maces, so you're not the only one with a blunt force weapon. Though if you really wanted to change her weapons to something sharp later on, there is always the pickhammer, which would be similar in fighting style to the hammers, which would reduce her adjustment time when it comes to learning a new weapon.

Oooh. I love her weapon now that I've seen it. That's awesome.
