Rey’s saber is rebuilt offscreen with barely a hint of the damage it sustained and no mention of that damage in the film.

Except its literal belt serves as a reminder of Rey’s failure in TLJ, and how much she’s grown from that.

Kylo’s mask, far from being reforged as a symbol of Kylo’s status as a new leader of the First Order, is instead a symbol of his regression back into a mere henchmen for a greater power.

Except Kylo does not serve Palpatine. He literally tells Rey “I have other plans” and asks for her help in defeating him on the hangar.
