An Excellent Reference Tool

Soon after High-Security Mechanical Locks: An Encyclopedic Reference was published, I purchased a copy as a reference tool since I am a high security lock collector. I consider the book to be an essential reference manual for high security locks insofar as it is comprehensive and detailed. The book fully explains the workings and components of high security locks. The explanations are in-depth and very understandable. The author has assigned a security rating (from 1 to 5 with 5 being the most secure) to each lock. I found this security rating to be very helpful and accurate in terms of the pick resistance of locks. The photographs in the book are outstanding and exceedingly informative. Having the book affords me the opportunity to learn more about high security locks from around the world that are extremely difficult to obtain and it assists me in expanding my lock collection and knowledge on the subject. Assembling such a vast array of information and photographs in one place concerning high security locks is quite an accomplishment. Other books concerning this topic have primarily discussed how to theoretically pick/defeat high security locks but have not delved into how such locks operate. Finally, there is a book available that offers comprehensive information on the inner workings and details of high security locks. I recommend this book wholeheartedly to all persons interested in high security locks.

A must have book

This is one of those books that is destined to be a highly prized possession of every locksmith, collector, and locksport enthusiast out there. Packed full of detailed descriptions and images, the author has provided a very detailed description of the workings of every major mechanical locking system around.

Well worth the purchase and well worth the read!

Best book on High Security locks I have ever seen

I have been a locksmith, lock collector and historian for 44 years and this is the best book on high security locks I have ever seen. It is hard bound and reads like a textbook. Photos and well-written explanations throughout. Covers locks from the 1800's through present day, from all over the world. I can't think of a lock or cylinder that was missed and everything is totally accurate. If you are interested in locks this book is a MUST HAVE.
