Kamui Shuriken

Through the use of Susanoo, Kakashi is able to create several large projectiles shaped like Obito's Mangekyo Sharingan, which he imbues with Kamui. Due to this structure, the tools act in a similar manner to that of a shuriken when thrown by Susanoo — rapidly spinning towards the intended target before cutting and instantly warping them into Kamui's Dimension on contact.
