it's wild how zweihander looks like polearm more than sword use. Wonder if that was sword technique diverging as some evolution of longsword?
naginata/nagimasa might wind up equivalent to zweihander, a long blade for big sweeping circular movements that you can shorten through your grip in a pinch - something in between halberd/yari and sword (especially because katana are shorter weapons). Now I'm wondering if no-dachi were way more swordsmith bragging rights to show up as often.
