I think
Robot Wars allows FlameThrowers. I don't watch it that often anymore, but I'm pretty sure I saw one the other night when I caught it on. There is a guy that dose a "art" show using Robots with every thing you can think of including Meachine Guns. If I see the link for it again, I'll post it. Big Problem using Saw Blades is getting enough pressure, you end up pushing the other bot before it actual cuts the other bots armor. I'd like to see one use something like a big stun gun and just blow the other bots System board. Tho I'm sure there is a rule about that.
