Madara Uchiha and have been seen wielding a large gunbai, about 3/4 of their height and almost of their width, with the pole being twice that length. Madara's had a chain attached to the handle that appears to have been connected to his kama, whereas Tobi's chain appears to enter his sleeve.

Ryun Uchiha uses a gunbai the same size as Tobi's and Madara's, which is red in coloration and has a black Sharingan imprint on it; much like Madara's own. When not in use, it stays attached to his back. Izuna Uchiha was said to use a small gunbai.

Madara uses his gunbai to create gusts of wind, block projectiles and as a melee weapon in combination with his kama.
