[1] Wielded by the male creator-god Izanagi, this blade is used to cut up the infant Fire God Kagu-Tsuchi after his birth burns Izanami to death.
[1] It cuts the Fire God into multiple pieces, creating eight volcano-gods.
The name of the ten-fist sword wielded by Izanagi is given postscripturally as Ame-no-ohabari, otherwise known as Itsu-no-ohabari.
Itsu-no-ohabari (who appeared previously as a ten-fist sword) here has the mind and speech of a sentient god, and he volunteered his son Takemikazuchi for the subjugation campaign.
Takemikazuchi was accompanied by Ame-no-torifune [ja] "Deity Heavenly-Bird-Boat" (which may be a boat as well as being a god).
