What Non-slip loop knot means
Instead of cinching tight to the eye, this knot locks down on itself and keeps a fixed loop in front of the fly. Most anglers use it on streamers and some nymphs when they want more movement from the fly.
Tie it with an overhand knot in the tippet, pass the tag through the eye, then back through the overhand. Wrap the tag around the standing line several times, return the tag through the overhand again, then snug it down while controlling loop size. Trim the tag close once it’s seated.
Why it matters on the water
A loop at the eye changes how a fly swims. Streamers tend to wander, kick, and pivot more on short strips and on the pause, especially patterns with bulky heads or wide profiles.
It’s a practical choice when a snug knot can “hinge” the fly and make it track stiffly. The tradeoff is a little more hardware at the eye, so it’s not everyone’s first pick for tiny dries or very small nymphs where a tight, compact knot helps keep things neat.

- Clinch knotA clinch knot is a simple knot for tying tippet or leader to a fly’s eye. It’s quick to tie and common for dry flies, nymphs, and small streamers.
- Davy knotA compact tippet-to-fly knot that uses a simple overhand structure. It’s popular for tiny flies because it’s quick to tie and uses very little tippet.
- Improved clinch knotA common knot for tying tippet to a fly. It’s a clinch knot with the tag end passed back through a second loop before tightening for a more secure finish.
- Orvis knotA tippet-to-fly knot that uses a doubled line through the hook eye, then a tuck back through a loop. It’s known for good strength with less twist than a clinch-style knot.
