Eye Crosser Knot

Eye Crosser

Finished structure

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

  1. Pass the line through the hook eye, leaving a long tagThe line passes once through the hook eye, with the standing line on one side and a long tag end on the other.
    1Tag end
    2Standing line
    Move 1 of 1Pass the line through the hook eye, leaving a long tagYou should now see: The line through the eye once, with a long free tag hanging on the far side.

    Step 01

    Pass the line through the eye of the hook, leaving a tag long enough to go through the eye again and wrap back around the lines.

    You should now see

    The line through the eye once, with a long free tag hanging on the far side of the eye.

    If it goes wrong

    Leaving too short a tag. After the second pass and the wraps there is too little left to hold, and the tag slips out during tightening.

    Fix: Pull more line through the eye before the second pass. If the tag has already slipped out, start again with more tag.

    Why: The tag makes a second pass, lies back along the standing line and then wraps both lines, so it needs more length than a single-pass knot.

  2. Pass the tag through the eye a second time, the same way, beside the first turnThe tag goes round the outside of the eye wire and through the eye again, so two turns of line lie side by side on the wire.
    1Two turns through the eye
    Move 1 of 2Pass the tag through the eye a second time, the same way, beside the first turn
    Lay the tag back alongside the standing lineThe tag leaves the eye and lies straight alongside the standing line, the two lines parallel and running away from the hook.
    1Tag laid back
    2Standing line
    Move 2 of 2Lay the tag back alongside the standing lineYou should now see: Two turns lying side by side on the eye, and the tag running back parallel to the standing line.

    Step 02

    Pass the tag through the eye a second time in the same direction, then lay the tag back alongside the standing line.

    You should now see

    Two turns of line through the eye lying next to each other, and the tag running back parallel to the standing line.

    If it goes wrong

    The second turn riding over the first in the eye, or the tag twisting around the standing line. The turns stack on top of each other instead of sitting side by side.

    Fix: Pull the tag back out of the second pass, feed it through again beside the first turn, and lay the tag flat along the standing line.

    Why: Two turns side by side share the load on the eye. A turn lying over the other is pinched against the metal when the knot is pulled.

  3. Wrap the tag three times round both parallel lines, back toward the eyeThe tag turns back at the end of its lay and wraps three times round the standing line and the laid tag together, working toward the eye.
    1Three wraps round both lines
    2Tag end
    Move 1 of 1Wrap the tag three times round both parallel lines, back toward the eyeYou should now see: Three neat wraps round both parallel lines a short way from the eye, with the tag end free from the last wrap.

    Step 03

    Wrap the tag end two or three times around the two parallel lines, the standing line and the tag lying beside it, keeping each wrap next to the last.

    You should now see

    Two or three neat wraps around both parallel lines a short way from the eye, with the tag end coming free from the last wrap.

    If it goes wrong

    Wrapping only the standing line instead of both lines, or letting the wraps cross. The wraps slide loose along the line as soon as the tag is pulled.

    Fix: Unwind the wraps and lay them again around both lines together, each one beside the last.

    Why: The wraps bind the doubled-back tag to the standing line. When the knot is pulled tight they bed down and hold the tag in place.

  4. Pull the tag to snug the wraps, then wet the knotThe three wraps close up against each other round both lines, still a short way from the eye, with the tag end free.
    Move 1 of 2Pull the tag to snug the wraps, then wet the knot
    Pull the standing line to slide the knot to the eye, set it, test it, trim the tagSlid down and pulled tight, the three wraps sit close behind the two turns on the hook eye, with the tag trimmed short.
    Move 2 of 2Pull the standing line to slide the knot to the eye, set it, test it, trim the tagYou should now see: A compact knot sitting on the eye, the wraps bedded evenly, no movement on a firm pull, and a short tag.

    Step 04

    Pull the tag to snug the wraps, wet the knot, and pull the standing line to slide it down to the eye. Pull the tag and standing line firmly to set it, test it, then trim the tag close.

    You should now see

    A compact knot sitting on the eye with the wraps bedded evenly, no movement under a firm test pull, and a short tag.

    If it goes wrong

    Pulling hard on dry line, or trimming before the test pull. A knot that has not bedded down moves along the line when it is loaded.

    Fix: If the knot moves or the wraps look loose after the test pull, cut it off and tie it again.

    Why: Wetting lets the wraps slide into place without heating the line. The final pull on both the tag and the standing line locks the wraps down behind the turns at the eye.

Failure modes

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

Braid-terminal family

Braid at the eye with extra passes so the slick line cannot slip.

  • !Passes never crossed through the eye
  • !Tag not locked after the extra braid passes
  • !Used on a small eye that cannot take the bulk
Fails when
  • !Wraps around the standing line only, so they slide loose when the tag is pulled
  • !Tightened dry or not bedded down, so the knot moves along the line under load
  • !Second turn riding over the first, so it is pinched against the eye when loaded
  • !Tag left too short, so it slips out as the knot is tightened
Geometry

  • Crossed strands in the eye

    Scores the line at the first hard turn

    Two clean eye passes, then the lock around the parallel pair · step 02

  • Eye too small for two passes

    Will not seat, or cuts at the eye

    Hardware must accept the doubled pass or this is the wrong terminal · step 01

  • Lock tied on the wrong side

    A slip, not an Eye Crosser

    The lock around the parallel strands is the finish · step 03

If you saw this

  • Knot will not seat or scores at the eye

    Check

    • ?Two parallel strands in the eye
    • ?Lock butted to the eye

    Then

    • →Retie on larger hardware
    • →Use Palomar or Uni instead

  • Finished check failed — Missed eye cross

    Check

    • ?Eye-crossing path completed as designed
    • ?Seated without open loops
    • ?Tag exit correct

    Then

    • →Retie. Missing the eye-cross path removes the knot's holding geometry.

  • Crossed strands in the eye

    Check

    • ?Scores the line at the first hard turn
    • ?Inspect step 02

    Then

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

  • Eye too small for two passes

    Check

    • ?Will not seat, or cuts at the eye
    • ?Inspect step 01

    Then

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

  • Lock tied on the wrong side

    Check

    • ?A slip, not an Eye Crosser
    • ?Inspect step 03

    Then

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

What it earns its place with, what it costs, and what to reach for instead.

Best for
Hook to lineHigh strength
Not ideal for
  • Tiny fly eyes

  • Leaving too short a tag, so it slips out during tightening
  • Laying the second turn over the first in the eye instead of beside it
  • Wrapping only the standing line instead of both parallel lines
  • Pulling hard on dry line, or trimming before the test pull
Alternatives
  • Trilene KnotIntermediate

    Tying monofilament or fluorocarbon line to a hook, swivel, snap or lure, with two passes through the eye

  • Palomar KnotBeginner

    Ties line to a hook or lure with the line doubled through the eye
