I'm going to turn this back to normal article. Even if it might be stub, beam saber is too common to restricted it to UC.
Currently, one curious detail turn up from ビームサーベル & Wikipedia:ja:ビームサーベル is that FC beam saber is actually "pseudo beam" made from nanite which would explain its flexibility and why sometime it can be touched without damage at all. Too bad, neither article cite their source.--My girlfriend was a loli. 14:18, October 28, 2020 (UTC)
