Give it the usual 2h-animation because it's just so stupid to see ur char using the polearm-animation for such a short sword. I mean, why the hell would someone grab that weapon with 1 hand on the blade and 1 on the liddle wooden thing (Lol, got no idea how to translate that xD). I don't know if there are any other short weapons like that with the polearm-animation, but if there are, change them, too.
