How would you feel if he somehow gives it to kuina?
She was originally the one who picked it out and wanted to buy it so it could be cool if it somehow went back to her.
It could be a situation where a stronger blade the same grade his other 2 is calling out to be weild by zoro. With instead of zoro just taking it and leaving sandai to the side to collect dust he decides to give it to someone he believes is worthy aka Tashigi
It could be a cool moment between the 2 where zoro not only trust her enough to take a blade he cares about so much but also shows how much he respects her strength as a swordsman. Knowing she’d be able to handle it and make sandai content with her
Killing 3 birds with one stone
- Cool meaningful moment with Tashigi
- Gets another great grade blade
- Sandai gets a respectable send off
