There are eight others, each a different weapon. Twin swords, a dagger, a kendama, a sword, an axe, a set of cards, leg guard, and a chakram. ... Although if any were to show up here... it would likely be any of them aside from the twin swords and the kendama.

Though ... I don't honestly know how likely it is for any of them to show up at all. This was probably more of a fluke than anything else.
