Clinch Knot

Simple clinch · Basic clinch

A quick knot for tying a hook, lure or fly to mono or fluoro line, when speed matters more than the improved clinch's extra tuck. Not a knot for braid.

Terminal · Beginner · Monofilament / Fluorocarbon · 4 steps

Finished structure

Drawn from a rope model of this knot: which strand passes over which comes from where the rope actually lies.

  1. Push the line through the hook eye and fold the tag back beside the standing lineThe line passes through the hook eye and the tag end folds back alongside the standing line, with plenty of tag left for the turns and the tuck.
    1Tag end, pulled through
    2Standing line, to the rod
    Move 1 of 1Push the line through the hook eye and fold the tag back beside the standing lineYou should now see: Tag and standing line lie side by side, pinched a short way above the eye, with a long tag free.

    Step 01

    Push the line through the hook eye and fold the tag back alongside the standing line, leaving enough tag for the turns and the tuck.

    You should now see

    Tag and standing line lying side by side and pinched together a short way above the eye, with the hook hanging below.

    If it goes wrong

    Pulling too little line through the eye. The turns use it up and the tag is too short to tuck back through the loop above the eye.

    Fix: Pull more line through the eye before you start. If the tag has already run short, undo the turns and begin again.

    Why: Holding the tag and standing line together keeps the loop above the eye open while the turns go on.

  2. Wrap the tag round the standing line about seven times, working away from the eyeSeven open turns of tag spiral along the standing line away from the eye, leaving a small loop beside the eye, with the tag end free past the last turn.
    1Seven turns about the standing line
    2Small loop beside the eye
    Move 1 of 1Wrap the tag round the standing line about seven times, working away from the eyeYou should now see: Seven even turns spiral up the standing line, with a small open loop between the first turn and the eye.

    Step 02

    Wrap the tag around the standing line, moving away from the eye. Make about seven turns, at least five, and seven or eight on light line.

    You should now see

    Even turns spiralling up the standing line, each next to the last, with a small open loop left between the first turn and the eye.

    If it goes wrong

    Losing count, or letting the turns overlap as they bunch up. Too few turns let the knot pull out, and crossed turns do not close evenly.

    Fix: Unwind and wrap again, counting each turn aloud and keeping light tension on the tag.

    Why: The turns are what grip the standing line. Light line gets more of them because thinner line has less surface to hold with.

  3. Bring the tag back and pass it through the small loop just above the eyeThe tag end arches back over the turns and passes through the small loop between the eye and the first turn, coming out behind the standing line beside the eye.
    1Small loop beside the eye
    Move 1 of 1Bring the tag back and pass it through the small loop just above the eyeYou should now see: The tag comes out of the small loop right beside the eye, and the turns are still loose.

    Step 03

    Pass the tag through the small loop just above the eye, between the eye and the first turn.

    You should now see

    The tag coming out of the small loop right beside the eye, with the turns still loose along the standing line.

    If it goes wrong

    Tucking the tag into the wrong opening so it does not pass through the small loop right above the eye. When pulled, the turns unwind and the tag slides free.

    Fix: Back the tag out and tuck it through the small loop beside the eye before pulling anything.

    Why: This single tuck makes the plain clinch. A second tuck back through the large loop along the turns makes it the improved clinch.

  4. Wet the knot, pull the turns tight down onto the eye, then trim the tagPulled tight, the seven turns close into a short barrel against the hook eye, with the trimmed tag end standing out of the small loop beside the eye.
    Move 1 of 1Wet the knot, pull the turns tight down onto the eye, then trim the tagYou should now see: A neat spiral of turns seated on the eye, the tag coming out of the small loop, and a short trimmed end.

    Step 04

    Wet the knot, pull it tight so the turns close down onto the eye, then trim the tag.

    You should now see

    The turns closed into a neat spiral seated on the eye, the tag coming out of the small loop, and a short trimmed end.

    If it goes wrong

    Pulling hard on dry line, or trimming before the turns have closed. The turns stay loose and can pull back open.

    Fix: If the turns unwind as you pull, stop, check the tag is still through the small loop by the eye, wet the knot and pull again.

    Why: Wetting cuts friction as the turns close, so they seat instead of heating the line.

Failure modes

When this family fails, it fails as these. The recovered end still outranks the name.

Clinch family

Wraps down the standing part, then a tuck that jams the barrel to the eye.

  • !Wraps walked or crossed — load on one turn of the barrel
  • !Barrel never jammed to the eye, so the tuck is decoration
  • !Tag never tucked, or the extra Improved / Trilene pass missing
Fails when
  • !Fewer than five turns, so the knot can pull out
  • !Crossed turns that do not close evenly
  • !Tag missed the small loop above the eye, so the turns unwind when pulled
  • !Tied in braided line, where the clinch wraps slip
Geometry

  • Uncounted or crossed clinch wraps

    The usual pull-out

    A plain clinch is wrap count plus the eye-loop pass, not a braid knot · step 02

  • Dry seat, or fished as if it were Improved

    Slips on braid; glazes on fluoro

    This is not an Improved Clinch and it is not a braid terminal · step 03

  • Tag never went back through the eye loop

    Unwraps — the finish was skipped

    The eye-loop pass is the clinch lock · step 01

If you saw this

  • Unwraps under load

    Check

    • ?Wrap count

    Then

    • →Retie with 5–7 wraps
    • →Upgrade to Improved Clinch

  • Finished check failed — Open gap above the eye

    Check

    • ?Neat spiral wraps seated to the eye
    • ?Tag exits cleanly without reverse wraps
    • ?Coil remains closed after pull test

    Then

    • →Retie. An open clinch fails on the first solid hookset.

  • Uncounted or crossed clinch wraps

    Check

    • ?The usual pull-out
    • ?Inspect step 02

    Then

    • →Retie. Do not dress a defective structure and call it seated.

  • Dry seat, or fished as if it were Improved
