Hey acid, pretty sweet blade, are you gonna model it? I kinda agree with louis, but farbtopf at the same time. I mean, it is cool to have those kind of weapons (whether it be for a hobby, collecting them, etc.), but I don't see a reason that you should need to carry it around. Like louis said, he has a pocket knife, which is a good idea, but if you really need a katana for self-defense, then you are pretty much paranoid. :p
