Iron Sand Gathering Assault: Wedge

Sasori uses his Third Kazekage human puppet to manipulate a large quantity of Iron Sand into a pyramid-shaped figure that lengthens towards his opponent while spinning from left to right.

Trivia

 * In the anime, Sasori performs a similar method, where he creates a similar shaped figure but has it spin in a single direction and merely uses it to try and drill it into the target.
