Yeah, those look like Emerald's weapons.

If there are actual classes of weapons, then it makes sense that some weapons are going to be similar. I mean, Qrow wields a scythe like Ruby's. Maybe Yang and Mercury looked at the same general weapon class, and Yang went with wrists while Mercury went with legs.
