In terms of Aura, I think all Aura can either have a physical effect, or an internal/etc effect. Irrelevant to the actual topic, maybe you could say that all types could be at one's disposal all at the same time, but maybe they haven't mastered the different types of it.

In this case, Aura doesn't seem to be as much of a shield of Jaune, as it is as much of a shield for Ren, since we all saw when he blocked the Taijitu's fangs with his hands using Aura. And, honestly, about the sharp weapons that could easily impale someone by having forceful physical contact with their bodies, but having it NOT ACTUALLY cut them at all? They're probably wearing, say, cut-resistant armor under their clothes (or it actually COULD BE all that they're wearing from the get-go) and the reason they fly back could be simply from the impact. Either way, any fight fought with the characters actually being attacked and swung at successfully with bladed weapons is better than having a "fight" where it's just blade clashes and dodges.
