Chakra Disruption Kunai

These chakra disruption kunai are custom-made kunai (特注クナイ, tokuchū kunai) utilised by Yūmei Kokūzō in conjunction with his Space–Time Ninjutsu: the Flying Thunder God Technique.

They are fashioned from the same material as the Rinnegan-derived chakra receivers, and are hence easily more resilient than normal kunai, and allow Yūmei to incapacitate those pierced by them through chakra-abducted influence akin to the other products of the ambiguous material.

The kunai itself has a cross shape, augmented for easier wielding and dual execution with various modes of nintaijutsu. One of the spikes is elongated and acts as the blade of the knife, while the other three act as the grip.
