Arrow wiki:
>For other uses, see Arrow (disambiguation). An arrow is a pointed projectile that is shot with a bow. It predates recorded history and is common to most cultures.

It is pointed or armed with an arrowhead at one end and with a nock or notch in the other. Arrowheads fit hunting and military purpose better than a mere point, which is mostly useful for target-shooting. Near the notch end are vanes which keep the arrow pointed in the direction of travel. There are often three vanes but many fletchings have four or even more. They were originally made from feathers but are now often made of plastic.
