Honestly, I expected a book about knifefighting, but this was more like "what happens when someone gets stabbed with a knife." It was an excellent book, nonetheless. Highly detailed as to demographics, weapon preferences, and skell tactics. The only thing missing was graphs! Interesting data on not one, but SEVERAL methods of using your jacket as a shield (incidentally, that's where the term "Cloak and Dagger" originated). More criminology than cutlery here, but still an outstanding read.
An entirely new approach to the subject--the author analyzes data he has collected in the form of anecdotes about violent incidents (many of which he repeats), to reveal statistical patterns he finds in weapons-related incidents in the Baltimore area. Interesting all around.
