Duncan loop: this is a sliding loop that allows the lure to have action in the water, but slides down
and tightens under pressure from a fish.

Form the loop by passing the line through the eye of the hook to make a bight of about 20cm (8in) for

the tying of the knot. Turn about half of the working end down back towards the hook, thus forming a
second bight, then take the end up and take five turns (figure 57.1) around both sides of the first bight.
Make sure that the working end passes through the second bight (figure 57.2).

To tighten the knot, hold the hook with a pair of pliers and pull steadily on the working end until the
loop and knot begin to tighten. Under normal pressure the knot will be secure and not slide, but when

fighting a fish the loop will slide down and tighten against the eye. You can reopen the loop with your
fingers for further use.
