Hidden Shadow Snake Hands

This jutsu allows the user to eject snakes from their wrist or sleeve, usually after a punching motion. The snakes are used primarily to attack from a distance and, being snakes, can inflict multiple poisonous wounds on the victim's body or hold them in place. The snakes can also open their mouths to extend Kusanagi-like blades.[/ref] Naruto Shippuden Episode 50 [ref]

This jutsu can also be classified as a variation of the Summoning Technique.
