What wrote:well i checked out the book the complete book of locks and locksmithing.
i am deeply disappointed in the fact that soo much of the book covers drilling techniques, and almost none of it is on picking.
I have the 2005 version. I first read an earlier version about 10 years ago. I became such a fan that I've purchase all versions since.
I think it's important to point out the Author stated several times that if it's got a key, it has the potential for being picked.
This is the book I would recommend for anyone before they paid for any training. I purchased the 2005 book for $18.
