Bob McNally's Complete Book of Fishermen's Knots, Fishing Rigs and How to Use Them (Used Paperback) - Bob McNally
Knots hold the dubious honor of being the potentially weakest link in your tackle. There are few moments in angling as deflating as discovering the small pigtail of curled line and vanished hook that signals the failed knot that caused the loss of a good fish. Knots can cut themselves into nonexistence, too, so that we may at first blame line or leader rather than ourselves in choosing the wrong knot for a particular purpose of erring in some step while making the tie.
