Any thoughts on what class Qrow taught is purely speculative, as we have never been told what he taught. We know he taught Ruby to use a scythe...but considering it's his own style, that's less an indication of him running a 'shop' or 'weapons' or 'fighting' class, and more Ruby thinks scythes are really cool and her uncle knows how to use one so he taught her when he saw she was interested.
