(1) The toolmaking quality of a specific raw material is based on the relationship of lithological attributes such as fracture type and grain size, as well as a qualitative determination of its suitability for use with certain techniques used to manufacture biface tools. Thus, raw materials that make concoidal fractures are fine grained, and are suitable for a complete repertory of flintknapping techniques (hard and soft percussion, pressure flaking) are assigned a high quality rating, while those with less favorable attributes are rated lower.
