combination locks

"This is a practical book but hard work and requires practice. Worth reading if you have a real interest in locks and will practice. Not for beginers; I bought this book first then came back to it."
-Stuart Gardner

"Having purchased similar books with varying degrees of satisfaction I easily rate this the highest. The text and pictures are independently useful and very complimentary. Its hard to call a book on lockpicking a must-read, but this should be a foundation for any learning of the subject."
