Non-slip Loop Knot

Use this loop knot to tie your fly on and leave it loose for maximum action. As the name implies, once you’ve eased the knot tight, unlike theĀ Duncan Loop, this loop cannot be adjusted. The Non-slip Loop works well with nymphs, streamers, and hair bugs.

First tie a half-hitch in the line, then pass the tippet through the eye of the hook. Pass the tip of the line back through the half-hitch so it points up the standing line. Make four wraps around the standing line and pass the tippet back through the half-hitch in line with the previous pass. Pull slowly the standing line and waste end to ease the knot tight.


Remember that all knots should be moistened before tightening. The idea is to reduce friction and heat generated as the fishing line tightens against itself. If a knot chaifs as it tightens it may significantly reduce the working strength of the leader. Old and sun damaged line will show poor knot strength.
