Lock Picking School in a Box! This is the easiest way to learn locksmithing/ lock picking, by removing a few pin sets from a lock, and one by one, add them back as your picking skills increase. Now, we’re pleased to offer our ""Locksmith School in a Box” to help the beginning locksmith develop all the skills needed to master pin-tumbler lock picking. The set includes five lock cylinders, the first of which has a single pin set in place, with each lock becoming progressively more difficult, the last lock containing a full number of pin sets. Also included are 4 picks, 1 tension tool, and the instructional book, ""Easy Pickings"". This “Progressive Learning System” is a proven method of learning.
