Good general knife books...

[corwise]

Looking if anyone had any recomendations for some good general knowledge knife books. Looking more toward tactical/military knives, something along the lines of history/styles/construction. Pretty much everything I can find online or at a bookstore is either "knife values" or "how to make," which isn't what I'm looking for. The only good one I've found is "Tactical Knives" by Dietmar Pohl, but no luck other then that. Thanks much.
