The Palomar Knot is regarded by anglers as one of the very best fishing knots due to its strength and reliability. The Palomar is used to tie a fly to a tippet or leader, or a line to a hook.
After passing the loop through the eye, use the loop to tie an overhand knot, then pass the loop over the hook and tighten it around the bight under the eye. The hook will freely rotate in the knot.
Some instructors of the Palomar Knot place the final loop against the hook shaft instead of down around the bight, but most fishermen feel that this limits the movement of the hook and recommend the technique as illustrated here. Learn how to tie the Palomar Knot following the 6 steps below.
