This was my second book about "alternative entering metods" (the first one was "Lock Bypass Methods"), but this is my Bible for sure! I'm not a long time lockpicker (I began March '99), but I guarantee, this piece will give you serious knowledge! It presents almost every kind of lock you will find, shows how they work and teach you how to pick them. Don't be disappointed if you fail to open your first ones, be persistent and you will succed. The illustration are as clear as crystal, so is the text. Steven Hampton gives you confidence by telling his experiences as a locksmith, making the book more informal, rather than just a "technical" guide. It is quite a thin book, but full of information, althought it seemed to me that it could be expanded. For further information on hi-tech locks, try "Advanced Lockpicking Secrets" by the same author.
