Shichiseiken

The is a broad and flat sword that was said to have once belonged to the Sage of the Six Paths himself, and has later come to be revered as one of the Treasured Tools of the Sage of the Six Paths. The item itself exhibits the unusual ability to sever a person's soul from their body, once it has first been drawn out by the Kōkinjō, where the victims most frequently said word will be inscribed directly onto the blade. The user would usually have to declare the sword to curse the recipient before using it to physically severs the target's soul from their body. In order to prevent the afflicted individual from observing what word has been written, the sword can be folded down the middle, increasing the chances that they will be imprisoned within the Benihisago if the specific word is repeated. However, as with the other four treasures, its usage consumes an enormous amount of chakra, so much so that an average person would die after only a short period.

The sword, along with four of the other treasures, were eventually acquired by Kumogakure, where at least four of them came into the possession of the Gold and Silver Brothers. As the siblings possessed immense chakra reserves and would later gain a portion of the Nine-Tailed Demon Fox's chakra, they alone were capable of wielding the treasures without fatal repercussions. When not in use, Kinkaku had a tendency to store the weapon within himself, drawing it from his own mouth only when actually needed.
