Yes, yes. Sasaki Kojiro was using a 150cm Nodachi, he uses a special technique called the "Tsubame Gaishi" or "Turning Swallow Cut" It's basically a very fast attack that contains three hits, very amazing considering he uses a nodachi. I'm trying to make a new one based on the technique, though I'll be using a standard katana and adding a fourth hit.
From two swift cuts downwards and a cut upward, it'll be two cut upwards. Though, I can do that the fourth cut gives me a big opening so I need to work on that...
I highly doubt that. If what Lance said before was true and this was in Korea, then the area would be quite mountainous terrain with lots of woodland. Don't go making stuff up yourself.
