They can count as Live Steel being steel period. Crowbars have no real edge to them but you still can't have them. Same thing applies for metal poles, batons, katars, shurukin, ect ect.
While "live" in the sci fi con circut means battle grade/edged weapons every major anime con I have yet heard of... Kumori, Sakura, Anime Evo, Anime Expo, ect all have the same policy. It's to much liability.
Basically it's their call on any prop once you get to con. As a note though, I made a half joke about peace bonding my gloves... me cosplaying Rude and his weapons being fists... I was heavily discouraged against it because if at any point I were to raise my hands in any way that could seem hostile, IE posing in the boxing pose from the game, it would count as breaking policy for peace bonded items and could be taken as an attack... evicting me from said con and possible legal actions.
