I have a mixed feeling an review about this book. Best way to describe the book, it is split in thirds - first third all text and some pointers on how to deal with situations. Perhaps some mental preparations, to-dos and don'ts. Second third is the part which more interesting. Defence techniques. The final third is a strange addition. It is some Bunkai techniques (kata applications).
I will focus on the defence section. I would say, the techniques shown in this book is perhaps better understood by those who have some degree of martial arts knowledge. To execute the moves or defence techniques and the attacks which are shown can only be related to if you have had practice. I already study martial arts and focus on the self defence part of my art. I am studying other techniques to broaden my knowledge and hence why I am seeking this from some books and some styles. What is interesting from all the research is the way some of the writers have been explaining the techniques or describing a situation.
I would say the instructor who wrote the beginning part of the book does provide good valid remarks. I am disappointed with the defence techniques. They are too focused on the style of the art the instructor teaches - Kissaki Kai. The description and images do not match and they are too many alternative descriptive text rather than images to show the effect. E.g. Hand grab. Description - Distract the attacker with a kick, or shout loud, or slap, or spit. Picture shows kick then next move. This could have been better shown with several examples. The pressure point technique shown was also poor.
I think some of the defence techniques are questionable and perhaps i have come across more effective and simpler techniques.
Overall there are some techniques i think are useable but most are average. With regards to pressure points (main reason why i bought this) there is very little i can actually take from this book. Even as a novice don't expect pressure point techniques which you will grasp and find easily accessible. Another point regarding pressure points - you have to feel the effect on yourself to know what it's like before you can use the techniques. If you get the techniques wrong - you are in trouble, therefore you need to know where and how these pressure points feel. There really is no substitute to real life practice.
The last third of the book is the worst section. Bunkai. How is Bunkai appropriate to those who do not study Kissaki Kai? I reckon this was a wasted opportunity and perhaps I would have liked to see more advanced and more aggressive pressure point techniques as the introduction to pressure points was too basic.
Should you buy this book? not sure. Buy this book if you want additional knowledge. There are some general self defence techniques which are useful, although not pressure points. Do not buy this book if you are looking for the answer to all your pressure point techniques.
