Dr. Robert Dohrenwend exemplifies a rare breed of scholar-warrior. You will find four chapters in this book devoted to weapons that have had enormous impact on world civilization: the sling, sai, walking stick, and spear. In each chapter Dr. Dohrenwend utilizes his academic research and practical experience to give the most complete overview of the weapons. This includes not only their history, but other aspects such as their purpose, design, effectiveness, cost of production, and uses in military and civilian settings.
