Alongside Kusanagi, there are two more ancient "tsurugi" that I know of.

Namely Prince Shotoku's Shichiseiken and Heishi Shourinken. They still exist and they're currently among Japan's national treasures.

...Minamoto no Yorimitsu's sword Dojigiri could also make it on, considering it's a real sword and (mythically) Yorimitsu cut off the head of Shutendoji with it. In general, only one of the Five Swords Under Heaven is in Touken Ranbu (that's Minazuki). Which is weird. Dojigiri, Onimaru, Otenta and Juzumaru are actually pretty famous.
