This is just a little detail but katanas aren't actually that sharp they are more for glancing blows and durability than being ubder sharp.
Ohhh... Dude...
Katanas are INSANELY sharp. I've gotten cuts by lightly touching the edge- seriously, blood was drawn, and I didn't think I was actually touching it yet.
I was at a tournament once, and a guy made a mistake when he was drawing the blade. The index and middle fingers on his left hand were on the floor before he felt any pain at all. He didn't even notice them until he slipped on the blood.
That's how sharp katanas are: they cut straight through bones like tissue paper. Fortunately for that guy, the nerves were sliced neatly, so a surgeon was able to reattach his fingers.
