I need weapons...

So, I have a character and I haven't chosen a weapon for her yet. I want something original. Here are the weapons that are already in use: dual wielding swords, bow and arrows, battle ax, spear, M16 rifle, machete/saw mix.
I need suggustions!! AUURRHHHH

A frickin' boomerang, yo. Or my personal favorite: a butterfly knife.

Butterfly knife would be perfect for her XD I could make it a dagger or something. I want a wide selection so, i'm still open.

I turned the butterfly knife into a dagger, what do you think?

I copied the wing-like design of the blade and curved handle but got rid of it's ability to fold.
