Well, the math is easy.... it's just that I don't know what to use to make the zanpakutoh. I mean, a combination of wood and steel? X_X;;;; Paint? Arghh....Making his zanpakuto would be a challenge. You're in engineering though, you can do it.
My big toe was always in pain because of the same thing, it was because of soccer though.
I tried to stand on my toes after watching ballet.So it hurts your toes 22? Does that mean you're tried it before?
