Shichiseiken

The is a light blue broad and flat sword with a brown talisman hanging from the bottom. By saying the verbal command, it can be used to sever the of those struck by the Kōkinjō, allowing the soul to be sucked into the Benihisago. Completing these conditions "curses" the victim; if they utter the word they have said the most during their life, they will be sucked into and trapped within the Benihisago. Whatever this word is will be inscribed onto the Shichiseiken's blade. The wielder can fold the blade to prevent the victim from seeing what it is. If their most-used word changes at any point, the inscribed word will be updated.

The Shichiseiken is revered as one of the treasured tools of the Sage of the Six Paths. All five of the tools consume enormous amounts of chakra when used, so much so that normal humans would die after using the tools for only a short period of time. When the tools later came into the possession of Kumogakure, only the Gold and Silver Brothers due to their large chakra reserves were able to wield the treasures without fatal repercussions. When not in use, Kinkaku stored the sword within himself, drawing it from his own mouth when needed.

After the Hano Uchiha carried the sword but it is know in possession of Sen Uchiha
