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 first used this jutsu to defeat Kakuzu a former member of Akatsuki, destroying two of his 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, with 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 the technique successfully makes contact, the victim becomes trapped in a vortex of wind chakra blades which attack the body on a cellular level so many times that even Kakashi Hatake is unable to count them all with his Sharingan eye. The wind chakra severes the chakra and nerve channels in the body. The Rasenshuriken is a vastly dangerous and powerful jutsu, due to the fact that Naruto could not originally throw the Rasenshuriken as the name would have people believe; thus creating the problem of the user being partially caught in the blast and damaged like the victim, though at a lesser level (mainly the arm used to direct the technique). However, as of Naruto's fight with Pain, Naruto has learned to overcome the damage to his own body by throwing the Rasenshuriken, thus completing the technique as well as perfecting its use. It is revealed in chapter 432 that the technique has a "dense and quick-spinning" characteristic. It seems that the new Rasenshuriken is more powerful than before seeing as how Kakuzu's body was constantly pierced by the previous Rasenshuriken while the Human Path of Pain's body was disintegrated except for half of his head.

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 due to the fact that it was still a melee range technique at this level. When Naruto used the Rasenshuriken twice on Kakuzu, it caused Naruto limited cellular damage and a few broken bones in the arm used to direct the technique. Thus the Fifth Hokage decreed the Rasenshuriken as a Kinjutsu, forbidding it as it could cause Naruto to be unable to manipulate 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. After revealing it in his fight against Pain, he was able to throw it, 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. In chapter 433, it is revealed that while Naruto is in Hermit Mode he can use the Rasenshuriken twice before being forced out of the mode, although this may not be totally true as after re-entering hermit mode Naruto used it twice, plus a Rasenrengan without running out of sage chakra, which gives reason to believe that because Naruto had shadow clones away in toad mountain the original didnt have as much sage chakra as he could possibly have. Ultimately meaning he could use the Rasenshuriken at least 4-6 times if he was in a full power sage mode with no shadow clones in toad mountain. Another explanation may be that 2 Rasenshuriken don't use up all of Naruto's Sage chakra, but what he has left is not enough to use it for a third time.

Trivia

 * When Naruto said the Technique name in front of Choji, the member of Team 10 told Naruto that he had thought that, since the name of the Technique had to do with a Shuriken, Naruto would throw it. Naruto was not able to do it at the time, but he is after his training in Myobokuzan.
 * It is a reasonable assumption that the reason Naruto is able to throw the completed version is because, like the Frog Katas, it uses the natural energy around it to maintain it for a given time.
 * During the training in Myobokuzan, an exhausted Naruto was shown in front of some mountains he had cut clean through. Some fans guessed correctly that Naruto could now throw the Wind Release: Rasenshuriken, but he didn't actually show the technique until his fight with Pain.
