I was just given a gift certificate to Amazon for 50 bucks. So I am looking for suggestions on what book about knives or knife construction would be the best use of the money. Ofcouse, I am not real sure that they even have any good knife books. The only real knife book I have is the "50 dollar knife shop", or something like that, my brain is not working real good right now. So what would be some good books that I could get. Thanks in advance for any suggestions.
