Correct Answer !
The tip of a projectile such as an arrow or spear used in an armament system which is manually powered. For archaeological sites in the Northeast United States, this includes both dart tips used in an atlatl projection system, and the better known 'arrowhead' which was used in a bow and arrow system. These projectile systems required different types of tips and thus differing manufacturing and maintenance technologies. For an example of a variety of projectile points, see "Prehistoric Structural Remains and Features: The Larson Farm".
