Knot Link

 Here's a knot link . Lefty Kreh is a very well known flyfishing guru and a very nice guy he wrote a book with Mark Sosin years ago.Their book was one of the first that actually rated knot strength. I still use it as a guide to show people how to tie knots.http://www.flyfisherman.com/skills/lkknots/

Thanks Mark! I guess I've got to learn a new one.
