Query: SAVE YOUR MONEY!!!!

I have to give this bookone star as it won't let me give it NO stars.From it's name you would think this would be a great book about the commando knife. WHAT A BIG let down!!! out of a book with 115 pages there are only 17 pages with pictures and drawings of commando knives.The majority of this book is about the people behind the knife. Do we, as a reader and knife lover need to know all or any of the military history of Col. Yeaton and where he was stationed and what he did as a marine. I don't think so.This is more of a bio of Kelly and Samuel Yeaton with a few pictures of commando knives to get you to buy it.SAVE YOUR MONEY!!
