Looking at the still of Jaune beheading the Giant Ursa, it looks like that there is a shining arc preceeding the blade's motion. I'm thinking that's some kind Dust- or Aura-based special effect, creating a wider energy blade around the physical blade.

Like all the other special features of his equipment, Jaune doesn't know about it, of course.
