Refinery and Internal Affairs stat boosts will be lost when swords reach toku (Lv. 20 or Lv. 25). You can upgrade swords to Kiwame after they reach Lv 60, this will reset their levels. Kiwame swords will not have a toku reset.

There is no need to start from scratch. Toku will only reset stats, not levels. Kiwame will reset both stats and levels but it is highly recommended to upgrade their stats before kiwame so it's easier for them to level up.
