I meant Pain Arc Sage Naruto, but Naruto by Boruto: Naruto the Movie is not rusty. Besides, that was most likely Kurama making a comment about his perception, as he obviously vastly underestimated Shin and wasn't even paying attention. They could have easily ended it, but I get the feeling he wanted Sarada to know that her father was a badass.

Besides, Naruto already knew about Shin's Mangekyou technique from clashing only once, he just didn't know he could mark other weapons and bend them to his will.
