ok , this is coming from someone who also appreciates the FFVII saga. yes, the Buster sowrd is very cool. no matter what steel you use it will be about 30 lbs if you want it to be a tru buster sword. i dont care who you are that would be too much for more than one swing. but if that is what you want to make then do it. my opinion wopuld be to make Sephirothes sword. it is actually a real functional and practical(in its own form) sword. it will still be heavier than most swords. but like i said clouds buster sword is very cool .
