I have both his
Complete Book of Locks and Locksmithing and his book
Locksmithing which is a revised edition of
Professional Locksmithing Techniques
While lock picking and forced entry is certainly covered, neither book is worth buying for the lockpicking info alone.
However both books are excellent for helping one learn about basic locksmithing terminology, techniques, and tools and equipment.
Locksmithing, while having a lot of the same info as
Complete Book of Locks and Locksmithing, seemed to me more like a textbook for a student at a locksmith trade school. It also has several chapters on actually running a locksmith business that
CBOLocks does not cover in as much detail.
Both books are available at
www.amazon.com and
www.amazon.ca (for Canadians) . When I last checked 2nd hand copies were also listed offering a significant savings.
