you don't want to accept that zoro is able to cut kaido only because of enma? ok
hyori said enma is the legendarry sword that gave kaido his only scar. but oden cut him with ame no habakiri too, that was entirely because of enma because when zoro first attack on kaido with santoryou it didn't do shit, and he said: "i gotta unleash this enma even more" he didn't talk about his other swords, meaning enma can affect other swords.
