Hello, this is actually my first post and I'm just getting used to everything so I hope this is in the right place.

I'm looking at soon starting work on my first robot and I was just looking for some clarification on rotating weapons. I've noticed a few references to some rotating weapons being banned as well as full body spinners, but I'm looking at a traditional circular saw blade, mounted vertically. Is this still allowed in heavyweight robots? If so, what actually is allowed in terms of those sorts of weapon?
