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.
Here's what the video covers, and some links for further information:
