From the makers of the Fisherman's Ultimate Knot Guide, here is new design variation (same 10 knots, a little more descriptive text on each knot, a little smaller profile, but no ruler). Waterproof plastic cards mean you can stash this little reference (just 2 1/4 x 3 1/2) in a tackle box or on a boat for years and not worry about it getting wet! Five cards are attached together in corner with a brass grommet. 10 most popular fishing knots are clearly illustrated: Improved Clinch, Palomar Knot, Uni-Knot, Dropper Loop, Surgeon's End Loop, Blood Knot, Rapala Knot, Double Uni-Knot Surgeon's Knot and Perfection End Loop. Every angler should have a set of these little cards in their tackle box!
