Wind Release: Rasenshuriken

The Wind Release: Rasenshuriken is a variation of the Wind Release: Rasengan, similar to the Great Ball Rasengan being a variation of the standard Rasengan. By manipulating the wind chakra of the Wind Release: Rasengan, Naruto was able to create four large points, making the Rasengan appear as a giant shuriken, the Rasengan in the center remaining a perfect sphere. Despite the name, because the Rasengan is a handheld jutsu, the Rasenshuriken can not be thrown, instead Naruto has to figure out a way to get close enough to his opponent and hit them. If successful, the victim becomes trapped in a vortex of wind chakra blades that attack the body on a cellular level. The wind chakra severs the chakra and nerve channels in the body.

The main drawback of the Rasenshuriken is that it is a double-blade sword. While it can utterly reap any opponent trapped in the vortex, it also damages the users body. When Naruto used the Rasenshuriken twice on Kakuzu, it resulted him with limited cellular damage and a few broken bones. The Fifth Hokage has sense decreed the Rasenshuriken as a Kinjutsu, forbidding it as it could cause Naruto unable to mold chakra at all.
