Finished structure

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

Failure modes

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

Interlocking-bend family

Two interlocking overhands or a Carrick lattice — tails on the documented sides.

  • !Tails on the wrong sides of the bend
  • !Broken lattice or a reef-knot form in disguise
  • !Undressed so one overhand takes the whole load
Fails when
  • !Both ends pass through the centre from the same side, so the two overhand knots do not lock into each other
  • !The bights are laid over each other instead of linked, so the ropes come apart before the knot is built
  • !The ends are left short on a join that takes a critical load
  • !It has taken a heavy load and must be untied, as it can jam tight enough to need cutting
Geometry
  • Same-side tails

    Bend will not lock and spills

    Each tail must exit opposite after its own-loop tuck · step 03

  • Started as a 6-and-9

    You tied a Zeppelin — keep it on purpose or retie Hunter's

    Hunter's overlaps tails; it does not start as a 6-and-9 · step 01

  • Expected to untie after a heavy snatch

    Jammed double-overhand, knife job

    If you must untie after load, use a Zeppelin · step 04

If you saw this
  • Bend spills, or will not break after load

    Check

    • ?Opposite working ends
    • ?Compact body, not a 6-and-9

    Then

    • →Retie opposite tails
    • →Use Zeppelin if you must untie after load
  • Same-side tails

    Check

    • ?Bend will not lock and spills
    • ?Inspect step 03

    Then

    • →Retie. Do not dress a defective structure and call it seated.
  • Started as a 6-and-9

    Check

    • ?You tied a Zeppelin — keep it on purpose or retie Hunter's
    • ?Inspect step 01

    Then

    • →Retie. Do not dress a defective structure and call it seated.
  • Expected to untie after a heavy snatch

    Check

    • ?Jammed double-overhand, knife job
    • ?Inspect step 04

    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

  • ·A bend captures two working ends. Holding is constriction and the seated wrap or barrel — not a closed-knot invariant.
  • ·Unequal diameters and slick pairs (braid to fluoro) are material problems. Crossing number does not rank FG against a Double Uni.

What topology does not predict

  • ·A Jones polynomial does not pick a braid-to-leader family.
  • ·Published retention bands stay as cited on the knot record. This page does not invent one.
  • ·Guide-click and tag-trim are field geometry, not topology.

Not for

  • ·Attaching a single line to a spar or cleat — that is a hitch
  • ·Reading this page as a recommendation from Decide
  • ·A join you must untie after a heavy snatch (Zeppelin)
  • ·Extreme diameter mismatch

Same pattern, different job
