In Naruto, Handsigns are one of the most basic movements to produce a jutsu. Handsigns direct the flow of chakra within the body, releasing the chakra out through the body's major discharge points, when the chakra is discharged, it takes on the appearance of a jutsu. Different combinations of handsigns can affect the look, element, and power of the jutsu, this is one of the two dependant factors of a jutsu; the other being chakras. Also Naruto is very stupid and I don't know why I even did this.
