Literally thousands of stone tools and implements have been found Kathu, South Africa. Here is a description of the tool making site: http://thenaturalhistorian.com/2014/12/18/how-rare-are-stone-age-artifacts-a-visit-to-a-stone-tool-making-center-at-kathu-south-africa/
I have found hundreds of stone tools in south Texas and northern Mexico. I have boxes of them, there is nothing I enjoy doing more than hunting arrowheads and stone tools. .
