Biface

A biface is a type of stone tool that has been flaked on both sides to create a sharp edge. This technique was commonly used by early humans for cutting, scraping, and other uses related to survival and daily tasks. Bifaces can vary in size and shape and are often made from materials like flint or chert. They are significant in archaeology as they help researchers understand early human technology, culture, and the development of tool-making skills. Examples of bifaces include hand axes and various types of knives used by prehistoric peoples.
