As you guys have probably noticed, Adam and Raven have both been seen with very distinct red blades.Qrow's weapon also reveals one in it's scythe form. Noticing all of this has made me think about what significance they may have.

My current theory, though with minimal evidence to work with, is that they have some sort of anti-Aura properties. I began to think this after Heroes and Monsters, when we see Adam completely go through Yang's fully-powered Aura and sever her arm in a single swing. Of course, this is meant to be a huge reveal of just how strong Adam is, but it also made me think about his weapon.

So far, we've seen very few of these. One in the hands of one of the world's most notorious terrorists, one with a cold vigilante with questionable morals, and one used conservatively by Vale's top spy. These are three people who seem to be the type who would battle other humans quite often, which is the only purpose an Aura-shattering weapon would serve, since the Grimm have no Aura. This may be a reason why we don't see them often, and the only protagonist wielding one seems to keeps it hidden as a last resort. A weapon made to be lethal to other humans, specifically Huntsmen and Huntresses, would certainly not be something that would be accepted.

This is only just a theory, and like I said, the only direct evidence supporting it is a single attack, but even so, there is something significant about these blades that we have yet to learn.
