Remove katana dash delimbing

Well one thing I've wanted to do for the katana was to give it a bit more variety in how it can be used. For instance, the katana sheath has no special attack and I would like for it to have one. But also, I'd like for the katana be able to be weilded with two hands by clicking it in-hand to switch like the quarterstaff, changing the special attack and other attributes.
