Do yourself a favor and send all of your tantous for kiwame training first, and if you have any leftover kiwame sets they can be used for the wakizashi and uchigatana if you want. Truthfully though, from what I've both observed and heard the wakizashi and uchigatana actually seem to be returning far weaker than their Lv. 99 Toku selves. They often go dead last in battle (even after ootachi!) despite what their stats might suggest unlike the kiwame tantous who will always go first. From what I've heard, it apparently takes until Lv. 60 or so for them to match the performance of a Lv. 99 Toku sword, which requires an absolutely insane amount of experience as you might've guessed. I've even heard reports from Japanese players that even at Level 99, kiwame wakizashi still aren't performing all that impressively so it really depends on if you think the time and effort is worth it or not.

Uchigatana have it even worse thanks to their even more massive experience requirements and the very unhelpful skill they currently possess which may cause them to lose most if not all of their troops quite often as a result if you happen to take them to a place with very heavy long-ranged attacks (like all of World 7). Meanwhile, a team of six kiwame tantous (after sufficient training) even after the nerf is strong enough for you to clear most of the World 7 maps as well as any night battles, so there you go.
