I ordered and have now read this book.  I recommend it to anyone who carries a tactical knife.  Bob Kasper omits all of the "stylized fluff" that would be forgotten and useless anyway in a down-and-dirty knife fight and sticks to the basics.  The lessons in this book reinforce some training I received long ago in another lifetime.  They remind one that a knife fight is not a balletic exercise but instead a damned violent and bloody piece of business in which it's best to be fast, accurate, and know what the Hell you're doing.
