Nintōjō

The, also known as the Staff of Two Heads in the English version of the anime, was the weapon which Jaken wielded. It could produce long streams of flame, and generated large floods of water. It was given to Jaken when Sesshōmaru saved him and his imp tribe from being slaughtered.

Physical description
It looks like the name it was given. On half of the top of the staff, sat the head of an old man, and on the other, sat the head of a once-beautiful woman. Although, it seemed the beautiful woman was more of an old woman with silky black hair. The staff was taller than Jaken himself.

Powers & Abilities
The Nintōjō didn't have many abilities. The old man head could spew fire whenever Jaken wished. When close to the grave of the Inu no Taishō, the old man's head laughed. But when at the wrong place, the beautiful woman shrieked.
