This book is one of the best sources for fishing knots, and knot tying, that you can find. The organization is such that you can find quickly several knot options for the task in mind, clear text that explains strengths and weaknesses of each knot and its use, and excellent diagrams that, with a little practice, make the knot yours. I give this book a 9 only because there are a few knots, and short-cut methods of tying them, such as the Turrel (sometimes called Turtle) knot, which are not included. If they were, then this near-ten would be an eleven. This book not only belongs on your book shelf, it needs to be in your tackle box.
