The National Locksmith presents The Ultimate Technitips Collection, Copyright 1997, no ISBN, 308 pages, 8 1/2" X 5 1/2".
This book is an assortment hints submitted by readers of the National Locksmith magazine. A locksmith ran into a sticky problem and found a clever work-around, and then sent the tip into the magazine. This is one of the collections, and Professional Locksmith Secrets Revealed was apparently another (I do not have a copy of it, so that is a guess). If this book had an index it be much better. To use it as a reference, the best one can do is have a stack of small post-it notes and make a set of tabs for any page of interest for later quick-reference, or maybe pencil in topics and page numbers inside the front cover. This book is sometimes offered as a freebie incentive to sign up for two years of the magazine.

The first 100 pages are automotive related, and being a twenty year old book a lot of that is out of date. The rest has some good items. At times it is a little bit like reading the "Day in the Life of a Locksmith" thread here. I can not understand why it has no index. The gun smithing equivalent to this book, the Brownell's Gunsmith Kinks series, not only include indexes but have cumulative indexes so looking up something in volume four will list where the topic is, if it exists, in all four volumes.
The National Locksmith sells the book for $39. I do not think it is worth that kind of money, but might be worth keeping an eye out for on eBay or Amazon.
