This volume should be commended for its successful and holistic effort in highlighting phenomena associated with pressure blade production through experimental, archaeological and historical investigations. This almost Herculean effort is clear, concise and marks a milestone in studies of blade technology. It is quintessential for anyone interested in studies of pressure blade production. (Christian Steven Hoggard, Journal of Lithic Studies, Vol. 2, 2015) The Desrosiers volume leans more strongly towards the Continental tradition, and in typical chaine operatoire fashion relies on empirical data to inform on lithic connaissances (knowledge) and savoir-faires (knowhow) to trace the culture historical progress of pressure blade flaking...Desrosiers provides an ideal opportunity to widen the investigative lens by considering technological approaches holistically.
