Ame-no-Ohabari

Ame-no-Ohabari (Japanese: 天之尾羽張), Ameno Ohabari, or Ama-no-Ohabari is a legendary Japanese blade that roughly translates to "Heavenly sword sharpened on both sides of the tip" or "Tail Feathers of Heaven." It is primarily found in the Izumo mythology. It is a kind of sword known as a Totsuka-no-Tsurugi or a "Sword of Length of Ten Fists" which seems to be distinguished by its length and having a double-sided blade.

In Mythology
Wielded by the male creator-god Izanagi, this blade is used to cut up the infant Fire God Kagutsuchi after his birth burns Izanami to death. It cuts the Fire God into multiple pieces, creating eight volcano-gods. When blood drips from the blade afterwards, the Sea God Watatsumi and the Rain God Kuraokami are formed.
