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.
Same family

Same failure class, different geometry. Open the plates — Diagnose still starts from the symptom.

This failed — start Diagnose

What holds it

  • ·The eye is hardware. The knot is an open tangle around that eye. Ends stay ends.
  • ·Seating (wet set, even wraps, tag orientation) is the mechanical record already on the knot. Theory adds no extra rating.

What topology does not predict

  • ·Trefoil / unknot classification does not apply to a Palomar or clinch.
  • ·Fluoro glaze, pigtail slip and nick-at-the-guides are forensic, not topological.
  • ·No strength percentage is computed here.

Not for

  • ·A free-swing lure loop — use a non-slip loop family
  • ·Using an invariant as a reason to keep a glazed terminal
  • ·Tiny fly eyes
  • ·Crowded hardware where a single-pass Uni or Palomar already fits

Same pattern, different job
