|Literal English||Sealing Kunai|
This is a kunai that was created by Raiko, and Yakumo Uzumaki. By implanting a seal on the kunai similar to the Flying Thunder God Kunai, when thrown it has a fuinjutsu sealing technique on it. When it comes into contact with a technique and the technique is sealed into the kunai, it is then in the user of the kuani control. By weaving a hand sign, Raiko or Yakumo can release the technique that was sealed into the kunai and direct it towards an opponent. Also a barrier can be added to the kunai to seal a larger technique.
Some of the main fuinjutsu that is on the kunai are Wind Release Technique Seal, Water Release Technique Seal, Fire Release Technique Seal, Earth Release Technique Seal, and Lightning Release Technique Seal.
