Controlled ballistics tests of ground, percussion-flaked, and pressure-flaked projectile point impact durability: Implications for archaeological method and theory

Ground stone projectile points can be found throughout the global archaeological record, but why they were selected for by prehistoric foragers has received little attention. Additionally, modern archaeological experiments have increasingly used ground points in lieu of knapped ones. Here, we present an experiment testing whether there is a difference between ground, percussion flaked, and pressure flaked points in terms of impact durability....
