" High-Security Mechanical Locks " comprehensively surveys and
explains the highly technical area of high security locks in a way
that is accessible to a wide audience. Well over 100 different
locks are presented, organized into 6 basic types. Each chapter
introduces the necessary concepts in a historical perspective and
further categorizes the locks. This is followed by detailed 'how it
works' descriptions with many pictures, diagrams and references.
The descriptions are based on actual dissections of the real locks.
The scope is limited to key operated mechanical locks, thus keyless
combination locks and digital locks are not covered. The book does
not deal with routine locksmithing topics such as installation and
servicing of locks. The sensitive area of picking and bypassing of
locks is dealt with only at a high level without giving detailed
information that would be unacceptable in the wrong hands.
* Comprehensive coverage of over 100 different types of 19th and
20th century key-operated locks, unified in a simple classification
scheme
* Detailed operating principles - clear 'how it works'
descriptions
* Manipulation resistance rating for each lock on a scale of 1 to 5
