Robert Terzuola's many years of experience as a custom knife maker are thoughtfully distilled into this handy and interesting book. "The Tactical Folding Knife" details and explains the many aspects of the design and construction of a modern folding knife. This book presupposes a certain level of technical proficiency regarding the use of the industrial tools needed to produce a folding knife of this type, but this fact does not detract from its accessibility for both the experienced machinist and the curious enthusiast. This book is broken down into chapters that illustrate not only the basic design and construction of a locking liner folding knife, but also includes chapters describing the characteristics of different component materials, helpful tips regarding specialized tools and a section on the care and maintenence of a finished knife. Although I don't think I will rush out and buy a lathe, I do feel that this book illuminates the subject in a way that can be appreciated by the layman as well as the experienced machinist
