User blog comment:Maki Kuronami/Nora's possible weapon?/@comment-3286116-20130813014623

Not only does it look like Nora, it also looks similar to warhammers I've seen.

The most relatable war hammer is the Orcish one from Skyrim, although the head is grossly oversized in this instance. To be honest, it looks like that hammer design mixed with the size of the Skull Hammer from Wind Waker. In any case, the other side of the head is more than likely a point, allowing for some piercing.
