What other hard substances, other than "metal", would be legal to use for this? There is come really tough polymers out there. It's got my curiosity up and running. Yeah, I know that's what killed the cat.

Yeah most times those biker boys sure don't fight fair, but so long as you know that going in (and are able to keep the fight one on one) you have a chance with or w/o your trusted G10.
