Trivia
The Ame no Habakiri (天羽々斬,Ame no Habakiri?, literally meaning "Snake-Slayer of Heaven/Takamagahara") is one of the most famous Totsuka no Tsurugi, appearing in Japanese mythology as a blade used by the Shinto god Susanoo to slay the legendary monster serpent Yamata no Orochi. "Haba" (羽々?) is an archaic term for "big snake" (orochi).
Beside its legendary status, it is a real sword, being enshrined as the shintai of Isonokami Shrine.
In Chapter 920 and Episode 893 a flashback of Oden is seen wielding a sword with a different tsuba. Whether this is a mistake or another sword is unknown.
