I was just using them to help my other swords level up. Before I knew it, Atsu is already 45 from 32 and Sayo is on 42 as the lowest level of my kiwames. It's slow, but you won't notice it because your focus is on the sword you are levelling. Also I used them to grind 7-3 a lot during the double drop rate/exp campaign to look for Kinky.

I grind on 5-4 or 6-1. 5-4 doesn't have any yari in it (excluding the KBC) so you won't have to think about spending resources on fixing too much.
