Bow & Arrow

A bow is a flexible arc which shoots aerodynamic projectiles (arrows or quarrels, sometimes stones) by means of elastic energy.

Use
Essentially, the bow is a form of spring powered by a string or cord. As this string is drawn, energy is stored in the flexible limbs of the bow; the energy is transferred to the arrow when the string is released, projecting it much farther than a weapon could be thrown.

The ninja of the Tsurugi Clan use Chakra Arrows, and some members of the clan can even use chakra bows. The art of using a bow and arrow is called  (弓術, Kyūjutsu).
