Shuriken Shadow Clone Technique

This technique was invented by Hiruzen Sarutobi, demonstrating his title as the "Professor" with its conceptualisation and efficiency. After throwing a single shuriken, the user duplicates it with their chakra, in the same way that the Shadow Clone Technique makes copies of the user; creating shadow clones is already difficult on its own, but specifically duplicating inanimate objects is even more difficult. In an instant, the thousand copied shuriken spread throughout the area, surrounding the target. Because the shuriken are physically real, the target is attacked from every direction, which they have almost no chance of completely avoiding.

In the manga, the duplicated shuriken simply appear out of thin air. In some anime depictions, the shuriken's creation is marked by a puff of smoke, just as happens when normal shadow clones are created.
