Bashōsen
Also known as, Banana Palm Fan. Revered as one of the treasured tools of the Sage of the Six Paths, the Bashousen consumes enormous amounts of chakra when used, killing normal humans upon doing so. It is able to generate all five basic elemental chakra natures in substantial amounts with a simple mental command.
Shichiseiken
Also known as the Seven Star Sword. One of the treasured tools of the Sage of the Six Paths. By saying the verbal command "curse" (呪え, noroe), it can be used to sever the word soul 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. Consumes enormous amounts of chakra from the user, resulting in the deaths of normal humans.
Kōkinjō
By saying the verbal command "Bind and Draw Out" it is able to draw out the word soul of anyone the rope has come into contact with, allowing it to then be severed by the Shichiseiken. The command is not mandatory. The Kōkinjō will not draw out the word soul of its wielder. The item generates an aura that can take the form of additional ropes, giving it a greater range. Like all treasure tools, it consumes enormous amounts of chakra and leaves normal humans dead.
Benihisago
It is able to take a person's word soul hostage by saying the verbal command "record". After the word soul has been drawn out by the Kōkinjō and then severed from their body by the Shichiseiken, it is absorbed into the gourd. 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. Saying a homophone of their most frequently spoken word, or even saying nothing at all for a certain amount of time, will also trigger the gourd's suction. If a victim starts to be sucked into Benihisago, the suction will stop if their most-used word changes. It can even keep those brought back with Summoning: Impure World Reincarnation sealed after the summoner releases the technique. Like all treasure tools, it consumes enormous amounts of chakra and leaves normal humans dead.
Kohaku no Jōhei
If the person responds, the pot records their voice and then seals them. This function is similar to the Benihisago, but more advanced as less preparation is required. The pot has a stylised kanji for "lightning" on it and a thick rope tied around its rim. It can even keep those brought back with Summoning: Impure World Reincarnation sealed after the summoner releases the technique. In the anime, it is filled with a dark liquid. The person that is sealed into the pot seemingly merges with the liquid. Like all treasure tools, it consumes enormous amounts of chakra and leaves normal humans dead.
