Editorial Comments (Author's Opinion)
This is a complete course in Rotating Constant Methoid Master Keying in book form. It is easy to read, having been written in a conversational tone, much like the Association classes taught by its author, upon which it is heavily based. Don OShall has personally trained some of the most successful master keying locksmiths in this country, and has written over 40 books and booklets for Locksmiths. This book is the definitive guide to this often misunderstood master keying technique.

That being said, the book is an excellent and useful reference text for the experienced Locksmith as well.
On a scale of 1 to 5 stars with 1 being Not Recommended" and 5 being "Buy NOW!", my opinion puts this at 4.5 stars.
