So something you clearly didn't see in the opening is in the scene with Qrow and Winter before we see old team QRTS(?), we can see Winter's weapon (some kind of rapier like Weiss's) and we can see Qrow's in a folded up posistion and it is clearly the same weapon from the picture. It is confirmed he uses a scythe from him teaching Ruby, to seeing it in the flash back story. This basically means his weapon is some type of sword/scythe.
