In the Stone Age, people used sharpened bone, flintknapped stones, flakes, and chips of rock as weapons and tools.
Such items remained in use throughout human civilization, with new materials used as time passed.
Cords and knots are implied by use-wear facets on perforated shell beads around 72,000 years old from Blombos.
Archeologists in Louisiana have discovered that early Native Americans used Alligator gar scales as arrow heads.
Many traditionalist archers choose heads made of modern high carbon steel that closely resemble traditional stone heads (see Variants).
Other classes of broadheads referred to as "mechanical" and "hybrid" are gaining popularity.
While "most attributes such as micro-residue distribution patterns and micro-wear will develop similarly on points used to tip spears, darts or arrows" and "explicit tests for distinctions between thrown spears and projected arrows have not yet been conducted" the researchers find "contextual support" for the use of these points on arrows: a broad range of animals were hunted, with an emphasis on taxa that prefer closed forested niches, including fast moving, terrestrial and arboreal animals.
