Bifaces: Stone Tools Worked on Both Sides

MVAC Senior Research Associate Dr. Connie Arzigian talks about bifaces—stones that have been worked on two broad sides, or faces. She describes what makes an artifact a biface and explains the stages of turning a large flake or block of stone into a tool ranging anywhere from a general-purpose knife to an intricately knapped projectile point.
