I disagree that his sheath/sword could ever be used a a bow. A bow needs a little bit of flexibility in order to be used the right way. With his sword in the sheath, it wouldn't be able to bend at all. Now if you mean use it as a crossbow, like have it on his arm and just point, I would also have to disagree. Besides the shields ability to fold into itself, there really isn't a lot of room for anything else besides a sword. Crossbows are complex and require a ton of moving parts and I just don't see his shield having room for all that stuff (especially if it was made a long time ago; I'm sure in the day the fact that it could fold up was amazing).

As far as Aura goes, I somewhat agree. I mean Aura has been shown to block attacks, but we haven't really seen it be used as anything but a personal force field. Ren for example seemed to be able to focus his Aura into one spot around his hands to block the snake, but Pyrrha and Jaune's aura seem to cover their entire bodies. This could mean that Aura simply lessons the damage caused by attacks, but doesn't completely stop them unless completely focusing your Aura in one spot. If he did spread his Aura out over a larger distance, it stands to reason that the shield would almost instantly break. I also mentioned below my ideas about his Semblance.
