>but what sword is Zoro using as his third sword?
Zoro's current swords are: Wado Ichimonji (Kunia's), Sandai Kitetsu (Cursed sword acquired in Loguetown), and obviously Enma from Wano. By the process of elimination, Sandai Kitetsu is the most likely to go, though I feel it was be better if he gained multiple sets of swords.
