Overview
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. Naruto used this jutsu to defeat Kakuzu of the Akatsuki, destroying two of Kakuzu's hearts. 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. The technique gives off a loud bell-like screech and is so powerful that it creates a storm around the area. If it is successful, the victim becomes trapped in a vortex of wind chakra blades that attack the body on a cellular level so many times that Kakashi Hatake is unable to count even with the Sharingan. The wind chakra severs the chakra and nerve channels in the body. The Rasenshuriken is a vastly dangerous and powerful jutsu. And this was when it was only half complete. As of Manga Chapter 432, Naruto has learned to throw the Rasenshuriken, thus completing and perfecting the Technique.

Drawbacks
The technique initially had two drawbacks, the lesser of which is the amount of Chakra needed to create the Technique. The greater drawback being that it was a double-edged sword. While it could utterly devastate any opponent trapped in the vortex, it also greatly damaged the user's body. When Naruto used the Rasenshuriken twice on Kakuzu, it caused Naruto limited cellular damage and a few broken bones. Thus the Fifth Hokage decreed the Rasenshuriken as a Kinjutsu, forbidding it as it could cause Naruto to be unable to mold chakra at all and possibly causing paralysis if important bones or organs were fractured.

Overcoming the Drawbacks
Naruto was later able to refine the Rasenshuriken while training in Hermit Mode; while revealing it in his fight against Pain, he was able to throw the Rasenshuriken, thus preventing any damage from the jutsu to his own body. Furthermore, the Rasenshuriken now expands a short while after being thrown thus increasing its radius of attack. However, this technique seems to tire out Naruto easily, as Pain commented on how his natural chakra levels decreased drastically after the usage of the jutsu.

Trivia

 * When thrown, the Rasenshuriken resembles the Destructo-Disk technique used by Krillin in the Dragonball series. Except for the core of the Rasenshuriken which is still shaped like a ball.


 * With Naruto being able to throw the Rasenshuriken proves that Choji's guess was right when he asked if Naruto can throw it when he first used it.
