Hi Rob

 

 This is actually an older book by Michael Echanis who had taught knife fighting and throwing to many special forces groups, the original first printing is hard to come by but they recently have reprinted it and it's available from Amazon.

 

 At one time this book was fetching up to 125.00 on ebay but the reprint is only about 25.00 if memory serves.
