From earliest Stone Age in Africa to 20th century California, our ancestors smashed rock to make tools. The tools from broken stones formed the most important survival kit ever invented and is surprisingly similar the world over. Elements of that kit live on today in remote corners of the globe among people close to the earth. The most important survival kit ever invented, it altered the very shape of the human species and for millions of years was truly a universal tool kit. The universal tool kit endured and accompanied man into the New World where it is strongly represented in all levels of archaeology and the ethnology of Native California. This book explores the origin, description and function of baseline stone tools and its practical applications and templates of manufacture. It also looks at stone age spear throwers and how they were used. Paul Douglas Campbell has studied California Native Americans for over 30 years. He is the author of Survival Skills of Native California and Earth pigments and Paints of Native California.
