His sword is apparently made by the Generic Props Company Ltd. It's japanese but totally straight, so he must be a ninja. The hilt is only big enough for one hand, even though the sword is enormous, so it must be made of space-age materials too. Also note how he wouldn't even be able to draw it, even though it's not strapped down or anything, so he's just wearing it as a declaration of his badassery to any would-be attackers. So much information just from observation!
