The term Paleo-Indian is an alternat… WebLithic reduction is the removal of a lithic flake from a larger stone in order to reach the desired tool shape and size. The beginning stone is called the flake lithic core. There are three steps to lithic reduction: Hard hammer percussion is the first step.
