Here's some info on the weapons I found on the site:
"In light of recent events, please think twice before considering the use of prop weapons in your skit. No live metal, guns (even unloaded), throwing stars, whips, nunchaku, or other “real” weapons will be allowed. Prop weapons and large staves will be allowed only on a case-by-case basis and for display on stage only. This means no swordplay, obnoxious use of gratuitous violence, etc, in your skit. If you have doubts, please ask the Masquerade coordinators. "
ahh but that's for the Masquerade 'n stuff
altho, I'm sure for just walking around in public 'n stuff the weapons themselves would need to be discreet. Basically if it looks like a toy gun, then it's okay, but if it looks even remotely real, then nope.
