A Gunbai (軍配, Gunbai; Literally meaning "army arrangement") or Gunbai Uchiwa (軍配団扇, Gunbai Uchiwa; Literally meaning "army arrangement fan") is a non-folding fan, usually made of wood. It was used in ancient Japan by samurai officers to communicate with their troops.

Uzu Uchiwa is the name of Honō Uzumaki and Kiu Uchiha's Father and Mother's gunbai. The two wooden weapons were made as a pair which interlocked. They were made with a special symbol on it to show the union of there family.

Honō Uzumaki went to his old childhood home and found this among other things. He began to play with it and quickly learned it could split apart into two. Hono eventually gave one two his younger brother when he left for the Akatsuki as a good bye gift from the brother that never was or will be there..
