Improved Clinch Knot: How to Tie It

The improved clinch knot is the classic everyday knot for tying hooks and swivels to mono and fluorocarbon, and the one most anglers were taught first. Tied properly it still earns its place, and it is faster than the palomar when you are threading small hooks with cold fingers.

Step by step

How to tie the improved clinch knot

  1. 1

    Thread the eye

    Thread the line through the hook eye and pull about 15cm of line through.

  2. 2

    Wrap the standing line

    Wrap the tag end around the standing line 5 to 7 times, working away from the hook.

  3. 3

    Back through the small loop

    Pass the tag end back through the small loop that sits next to the hook eye.

  4. 4

    Through the big loop

    Then pass the tag end through the larger loop you have just created. This extra tuck is what makes it the improved clinch.

  5. 5

    Wet, tighten and trim

    Wet the knot, pull it tight slowly against the standing line, and trim the tag.

Two rules apply to every knot: wet it with saliva before pulling it tight, because dry friction weakens mono and fluorocarbon at the exact point you need strength, and tighten slowly, then test with a firm pull before you cast.

How strong is it?

Retains around 90 to 95% of line strength on mono and fluorocarbon. Exact figures vary with line type, diameter and how well the knot is tied, so treat any percentage as a guide, not a guarantee.

When to use the improved clinch knot

Everyday hook and swivel connections on mono and fluorocarbon, especially lighter lines. Use 7 wraps on light line under 6lb and 5 wraps on heavier mono. Skip it on braid, where it has a reputation for slipping; that is palomar or grinner territory.

Improved Clinch Knot: common questions

On mono and fluorocarbon, yes: tied properly it retains around 90 to 95% of line strength, which is on par with the grinner. The usual failures come from too few wraps, skipping the final tuck, or pulling it tight dry, not from the knot design itself.

Braid is thin, slick and non stretch, and the clinch relies on friction that braid does not generate well, so the knot can slip under load. Switch to a palomar or grinner for hooks and lures on braided line.

Use 7 wraps on light line under 6lb and 5 wraps on heavier mono. Thin line needs more turns to build friction, while thick mono will not seat cleanly with too many.

The improved version adds one final tuck: after passing the tag through the small loop by the eye, you also pass it through the big loop just formed. That tuck locks the knot and is worth doing every time; the basic clinch gives up strength and reliability for no real saving.
