Measurable flintknapping for long pressure blades

Abstract

This chapter presents parameter studies carried out on medium to long pressure blades, obtained by using the approach and method of measurable flintknapping. Firstly, the extended range of possibilities of this method and the main characteristics of a new and larger double lever machine are described. Other subjects dealt with are the control of blade torsion, the correlation between the length and width of a blade and the fracture propagation force, the most probable locations of breaks and finally the relevance of tuning, stored energy and follow-through.
