Book excerpt: It has been over 20 years since a major work on switchblades has been published, and never has one showcased as many different types as this book. The book contains a history of the early cutlery industry in America; a detailed examination of the evolution of switchblades; and a user-friendly, up-to-the-minute, illustrated reference section that helps collectors and novices alike identify all kinds of knives, from museum-quality antiques to old folders that have been hidden in the attic for decades. Langston, a life-long knife lover and collector, provides an honest appraisal of over 160 autos based on maker, condition, markings, materials, functioning and availability. Perfect for collectors, enthusiasts, historians or anyone even considering buying or selling a switchblade.
