This archaeological publication covers the development, definition, classification, and world-wide deployment of the lithic bipoint and includes numerous photographs, drawings, and maps. Lithic bipoint technology originated 75,000 years ago, and it continued to the discovery of metal for tools. It was brought into the U.S. on both coasts; the Pacific Coast introduction was around 17,000 years ago and the Atlantic Coast was 23,000 years ago. This book presents and discusses bipoints from nearly every U.S. state. Bipoint function, usage, and resharpening are also presented. The book is indexed and has extensive references.
