First things first, this book is excellent. Sang H. Kim has no equal in his art, and I have nothing but full respect for him. Pressure points were a specialty of mine when I was still active in competitive martial arts, and while my outlook on fighting has changed over the years, it's best to end a fight quickly, and going for the vitals is the surefire way to do that. The presentation of this book is very well-organized, has many useful pictures, charts and photos showing every single pressure point [except two I know of that are best kept out of books to the public] and how to apply the strikes in real life situations. This isn't your standard martial arts book that shows you to 'do this if this happens', but it thoroughly explains everything and why you're doing it. My only gripe is with the photos and that they aren't in color, but black and white, so -sometimes- it's hard to see certain things, but usually everything's very clear.
But my main criticism is that this book is extremely dangerous, and I don't think it should've been released with this much information. Any martial artist of any rank can get it, read a few pages, think they're a killing machine, and then will either hurt someone else very seriously, or do something wrong and get hurt them self. Please, if you're interested in getting this book and have martial arts experience, ask your master about it if they know anything. As someone who was on the receiving end of a pressure point strike over 10 years ago, I still haven't recovered from a hit on my inner elbow, and can't hold my arm still without continuous shaking. But if you're using this book for reference and to know what points to keep more protected, that'd be the best reason to get this.
Again, the book itself is an excellent resource, and I wish it had been out when I was younger. Seeing just how many pressure points there are on the human body is incredible, and knowing that you're doing acupuncture in reverse with the knowledge on these pages isn't something to take lightly. Please use the utmost care if you plan on actually using the techniques in this book.
