Reader Reviews

"David has done a great job analyzing techniques and concepts from several martial disciplines and creating a truly functional self defense system that works under pressure with an uncooperative opponent. It is not just a collection of random techniques, but rather a well thought out systematic and conceptual approach to practical and realistic self defense. If you are new to self defense or are an inveterate martial artist, you owe it to yourself to study Functional Self Defense."
- James Wilson, Crescent City Eskrima
"This is David's second book on self defense, this one being focused on both weapon's defense and use. As in his first book, which I recommend as well, he is focused intently on functional techniques. Both are filled with very candid and sound advice on every topic they cover. This book covers some heavy topics.... Unarmed self defense against a knife, unarmed defense against a gun, etc.... David pulls no punches; the techniques in here could save your life if you will take the time to really practice and learn them....I anticipated the realease of this book and I was not disappointed. I will prize this book for years to come. I'm looking forward to putting it into some serious practice with my own students..."

"Mr. Erath has done yet another excellent job of showing what is realistic in terms of self-defense...You can tell that Mr. Erath has spent a good deal of time training and figuring out what will actually work and what is just pure nonsense. He is committed to helping people realistically and functionally learn to defend themselves. Buy the book, you won't regret it."
- Kristopher Eaton, Amazon.com Reveiw

*Note: The e-book version of the Ultimate Guide to Unarmed Self Defense is a PDF e-book, optimized for printing or viewing on a desktop, laptop, or tablet. It can be uploaded to an e-reader (Kindle, Nook, etc.), but due to the large number of images, viewing on a full sized screen is ideal. I chose to use the PDF format instead of a .mobi or other e-reader format in order to maintain the quality and layout of the images for instructional purposes. Due to the high number of high quality images, the book is 123MB.
