I don't know if I just don't understand Katana's, but the Katana, sheathed at your side, seems backward.

If you look at it, the bend of the blade goes up, in a way that would make it really awkward to pull out. To me, the bend should be in the other direction so that you could quickly unsheathe it for the Samurai's quick attack.

Does that even make sense to any of you? Is that the "Samurai's way", because they swap the direction when in battle, or some shit like that?
