The Flintworker

From the "Tools of Early Man Series" by Don Crabtree
In The Flintworker Don Crabtree demonstrates the making of stone tools using the cone principle which predicts where and how stone will fracture.
Originally produced as a motion picture in 1972 with National Science Foundation Grant. "One in a film series on the subject of lithic technology."
Don Crabtree (1912-1980), a renowned flint knapper, paved the way for scientific analyses of archaeological stone tools around the world. Born in Heyburn, Idaho in 1912, he moved to California in 1931 and soon became the supervisor of the vertebrate and invertebrate laboratory at the Museum of Paleontology, University of California, Berkeley. In 1939 he was diagnosed with cancer and returned to Idaho, where he focused on the craft of flint knapping, the reduction of stone to form tools. Crabtree practiced making arrowheads, spear points, and eccentrics by the hour.
