Projectile point
In
archaeology, a
projectile point is an object that was hafted and used either as
knife or
projectile tip or both. Occasionally, projectile points made of worked
bone or
ivory are found at archaeological sites, but generally the term is reserved for a refined chipped-stone
biface. Projectile points fall into two general types: dart points and arrow points. Dart points are defined as those bifaces which were used to tip spears and
atlatl darts. Arrow points are smaller and lighter than dart points, and were used to tip arrows. Both dart and arrow points come in a bewildering variety of styles, which vary according to geographic area.
