I think like that too, his sword is well decorated, afteral we know that it's not a ordinary saber. But all shown Meitous' are katanas or other sword types that looks like them. Maybe all the named swords are katanas too, and for Kokutou Yoru, If I'm not mistaken I read in this wikia that it's a katana with decorated hilt
