There's no indication it posssessed some special properties akin to the original Kusanagi. Though it could be the case (since TB was also called a type of Kusanagi, which means there are different Kusanagi blades), but currently, no explanation of it was ever provided.

P.S. Even then, like BakumatsuWarrior pointed out, Sasuke's initial Kusanagi and the Kusanagi of his adult form are different blades, their properties can differ as well. We only know for sure one property they both share and that's simply a possibility of channeling Lightning Release through it. But it's not really special because technically chakra can be channeled through any weapon, the weapons like chakra blades are just easier to exploit for this task.
