But we still have samurais with a sword
Do you mean from the main Wano characters ?
We have kawamatsu for Hybrid style. Fukurokuju is a ninja,doesn't have a blade ,so he must have some unarmed combat style as well.
As for the "fodder",considering Oda wouldn't show them,better to not have any .
While I think Oda draws better nonblade fights, I don't think this is really big deal. For the majority we will get unarmed combat thanks to the main cast anyway.
