Toku ni and toku san is an upgrade only available for Higekiri and Hizamaru, the other swords only got their toku upgrade for one time only.

The difference would be in the stats and the petals I guess? Both Hizamaru and Higekiri can change from a 2-petal swords to 4-petal rarity when you toku them...
