- Name: Chidori Sharp Spear (Chidori Eisō; Literally meaning "One Thousand Birds Sharp Spear")
- Type: A-rank, Offensive, Short to mid-range (0-10m)
- User: Sasuke Uchiha
- Debut (Manga): Chapter 343
Sasuke increases the range of his Chidori by using form manipulation to extend it into a blade up to 10 meters in length. This blade is capable of splitting into multiple additional blades upon contact with an enemy, drastically increasing the number of wounds it can inflict. However, each of these additional blades is proportionally weaker than a single focused Chidori. Like other Chidori-related techniques, this jutsu will numb any target it hits.
