Archaeologists frequently research these prehistoric societies, and the examination of stone tools is known as lithic analysis. To deepen our understanding of the cultural ramifications of stone tool use and production, ethnoarchaeology has been a useful research field.
Arrowheads, spearheads, hand axes, and querns are just a few examples of the numerous tools made from stone throughout history. Stone can be ground into tools or it can be shaped by a flintknapper into knapped implements.
