These are one of the five tools created and used by the Inagara Clan. Made from a special chakra absorbing material, they augment the wielder's water nature chakra. The dual prongs on top allow water to be expelled. The entire tool is hollow. Attacks using this tool mostly revolve around either sticking the prongs into the ground to create geysers of water, or blowing into the base to shoot water bullets. There's a handle near the base that is also hollow. Blowing into this slot will give the same results. Holding this handle allows the sasumata to be spun. Water can add to the spinning to make a water shield.
