Not to mention it is a sword and a shield, those aren't exactly weapons with a bunch of things to hide. I mean Jaune seems to have his weapons with him a lot (as shown by Cardin's bullying), so he has probably at least examined his weapons. Unless it has some kind of ridiculously complex activation sequence to give it additional abilities or it relies on something like Dust, Aura, or maybe even a Semblance his great-grandfather had for support, I'm sure Jaune or at least Pyrrha would have noticed something.
