Summoning Dagger

Summoning Daggers (口寄せ短剣, Kuchiyose Tanken) are a series of unique, custom-made kunai whose creation was commissioned by Kaidan Nomura. Their purpose revolves around the summoning of an individual's contracted beasts without the need of performing the typical, time-consuming method. To this end, the daggers each appear as curved, exceptionally light weapons with the contract-formula for a particular summoning printed upon the handle. This print, while it appears as nothing more than black "ink", is actually a special blend of paint mingled with the blood of the user, so that by simply conducting chakra through the blade, a complete summoning technique may be performed.

Kaidan Nomura has revealed an exceptional proficiency in utilizing these weapons, as he is able to control the flow of his chakra to such a degree that he can choose exactly when the summoning technique will occur. Due to this, he has commissioned the creation of dozens upon dozens of these weapons, and litters his battlefields with them so that he may summon as many bats as possible. Aside from Kaidan, only a few shinobi of Tenkūgakure have possession of these weapons, those being his students.
