Kamayari

Kamayari (鎌槍, sickle spear) is the first technique taught to Takumi Uchiha.

Usage
To use, the user would channel a huge amount of chakra to his hand, creating a concentration of chakra that becomes visible. Then by adding Water-natured chakra to it and shaping it in the form of a ball of concentrated chakra with multiple small razor blade like spears around it. Then, the user would begin propagating his chakra which would result in formation of wild stream of chakra with unusual blades, which produces a sound similar to gushing water. Finally, he would begin stabilizing the wild stream of chakra, causing it to warp around the users hand and take the shape of mild blue flames, and have shimmers of some kind flowing through them, giving them an appearance similar to rippling water. The core is of a distinctively dark blue and the ever oscillating outer sections are of a more light tone of blue. This stream then will be shot towards the opponent(S), unlike other ninjutsu's instead of harming or killing the opponent, upon impact it would tranquilize the opponent, weaken his killing intent, weaken a target by robbing its strength and capacity of movement and finally would slowly disintegrate their chakra.

Trivia

 * The kamayari (鎌槍, sickle spear) is similar to the jumonji yari. While it also had two protrusions shooting off the base of a main spear tip, in yari the offshoots were hooked back downward. The kamayari essentially is a yari with kama at the base of the blade to assist in hooking things. Generally the hooks are large enough to hold the head, neck or jaw (when in a tree) or to hook limbs of a swordsman on the ground, thus it is different in function in this respect from other types of yari. Also the kamayari was used to hook horsemen and dismount them.
