Boruto was given his Kama when he used the giant rasengan and beat momoshiki. Even though Boruto did the least in this fight-- he was holding a rasengan made strong enough by naruto and he attacked after sasuke used himself to create the opening. All boruto did was use the jutsu.

But Momoshiki him this new ability, and it is theorized that you get it from beating a otsutsuki. So how did Kawaki get it? There is no way he was able to beat an otsutsuki, only Sasuke and Naruto has a chance against any of them.
