This is a benchmark book on the subject by the late Charles Gruzanski. The use of a short chain with weighted ends employed by a trained practitioner can be deadly effective against an unarmed opponent, which this book will show. This book covers the art and science of the Japanese weapons fighting forms and employment of the short-chain and Shuriken. In the book the vital spots of the body are meticulously delineated, and the basic combat use of the chain is taught in graphic, easy to understand photographs and text. The proper methods of perforating your target with throwing darts/Shurikens are explained in detail. As well as how to construct your own "tools" of the trade. For the practicality of these techniques for the combatant is were these techniques fall short. As both methods require time, training and experience to get skilled, to be of any practical use in the short term. But it is somewhat entertaining training.
