The most famous Totsuka no Tsurugi sword is the one that Susano used when he killed off Yamata no orochi (eight-forked-snake) (the sword is also called 'Ame no Habakiri' [a heavenly sword to cut a monster serpent]; "Haba" means "a monster serpent").
最も有名なのはヤマタノオロチ退治の時にスサノオが使った十拳剣（別名「天羽々斬（あめのはばきり）」。"羽々"とは"大蛇"の意味）。
