/cgl/ - Cosplay & EGL

Hi /cgl/

I'm curious, how do you prefer to handle cosplay weapons of ludicrous size? Is there anything you can make them out of that isn't ungodly heavy but doesn't look like styrofoam or snap in half in a strong wind?

I ask because I want to finish off an existing Dark Souls armor I have, which I have already worn to some cons, with an iconic weapon from the franchise. Ideally this would be the Black Knight Greatsword I have pictured, but I'm not 100% set on that since it might not be realistically practical.
