Some books about fighting are heavy on philosophy, or history of a "system" or "style". I'm not making fun of them, because there are systems and styles that I like a lot.
This is a different sort of book. Little less talk, little more action.
The photos are perfectly good but they aren't museum quality. They aren't pretty at all. There is no consideration whatsoever to esthetics in this book.
This is a legitimate tough guy from a tough era talking about a bag of tricks. The book is heavy on demonstration in a LOT of grubby little pictures, and light on talk.
If you practice nothing but the techniques in this book, you'll be more effective than you were before.
Note that this edition probably doesn't contain the eye gouge waza. The author discusses and illustrates his favorite approach to an eye gouge, and the editors, in their infinite wisdom, left it out. They also left out an illustration of a groin attack.
My guess is that you'll find them on the internet if you look for them.
Anyway, if you've ever had an interest in expanding your bag of tricks, this is a cheap, easy, effective source.
And some of these are pretty nasty (if the editors took out the eye gouge and one groin attack, they left in plenty of other down and dirty stuff), so don't give this one to your eight-year old grandchild.
Just reading this book tells you AGAIN why you really, really don't want to get into fights. Somebody may have been reading the unedited version of this thing!
Don't buy this book if you want a coffee-table-sized, beautifully photographed book full of artistic martial arts techniques. This is straight-up tough guy stuff from another era. And this guy had a lot of experience and useful stuff between his ears.
A somewhat comparable book is "Strictly Street Stuff". This book makes fewer choices for you. It provides a smorgasbord of techniques, and let's you decide which ones you want to spend time practicing (because nothing works without practice).
