This book, written by LeRoi Price, fulfills the desire of many knives fans, who for years have sought information and knowledge on the mechanisms of folding knives, doing extensive searches on the web, which often gave only fragmentary and incomprehensible information.

 One of the most interesting innovations of last year was the 0456, produced by the American Company Zero Tolerance, and based on Dmitriy Sinkevich's custom model, "The Pole".

Amongst the most popular gentlemans' knives of the last decade, we cannot help but mention the Leek designed by Ken Onion and produced by Kershaw in over 12 configurations of blade and handle.
