The Pro-Knot Guide Cards feature six cards that are attached together in the corner with a brass grommet and demonstrate how to effectively tie different knots to fit certain situations. The 14 useful knots cover most any rope tying scenario: Bowline, Square Knot, Water Knot, Rolling Hitch, Sheet Bend (doubled version, too), Trucker's Hitch, Mooring Hitch, Tautline Hitch, Clove Hitch, Constrictor Knot, Buntline Hitch, Double Fisherman's, Figure Eight Follow Through and the Bowline on a Bight. A set of these Pro-Knot Guide Cards are great to throw in your backpack, keep on your boat, and store in the glove box of your car or truck to make sure you have them ready for anything that comes up!
