This page does not pick a knot for you. DNA, molecules, quantum braids and vortices stay off Decide.

Kryston Non-Slip Loop — what fails and what to do

Kryston Non-Slip Loop — what fails and what to do
Hook the Horizon reference plate
Fixed-loop family

A loop that stays the size you made, with a return that cannot cinch.

  • !Loop cinched around the hardware — action is dead
  • !Return path reversed, so it becomes a slip loop
  • !Fluoro in a lock that only behaves on mono
Fails when
  • !Tied in fluorocarbon, where NetKnots reports it failing well below the line's rating
  • !The tag went back through the overhand from the wrong side, leaving it free to run so the loop slides smaller
  • !Only one pass was made back through the overhand, so the loop slides smaller when the standing line is pulled
Geometry
  • Reversed return path

    A slip loop, not a Kryston

    The return is the non-slip lock on mono — reverse it and it cinches · step 03

  • Loop closed around the hardware

    Wrong sequence; action is dead

    Size the loop, then lock, without trapping the hook in a tight eye · step 02

  • Fluoro substituted for mono

    This lock is a mono knot — fluoro will not behave

    The Kryston non-slip we cover is mono; fluoro is a different family · step 01

If you saw this
  • Loop slips or the lock fails

    Check

    • ?Material is nylon
    • ?Loop still open under pull

    Then

    • Retie in mono
    • Use Kreh/Rapala if you must fish fluoro
  • Loop size shrinks under the first real load.

    Check

    • ?Look for: Loop size shrinks under the first real load.

    Then

    • Hold loop size while seating; verify return path.
  • Wraps bunch instead of lying ordered.

    Check

    • ?Look for: Wraps bunch instead of lying ordered.

    Then

    • Retie keeping wraps side-by-side.
  • Loop fails or creeps on fluoro/slick mono.

    Check

    • ?Look for: Loop fails or creeps on fluoro/slick mono.

    Then

    • Use a verified loop for that material.
  • Tag works free after repeated casts.

    Check

    • ?Look for: Tag works free after repeated casts.

    Then

    • Leave a safer tag and recheck mid-session.
  • Finished check failed — fluorocarbon is substituted despite the documented warning

    Check

    • ?loop remains the intended size after seating
    • ?wraps form cleanly in the reviewed mono-first system
    • ?tag and standing line leave the knot without crossed coils

    Then

    • Retie. unstable loop or material-specific failure.
  • Reversed return path

    Check

    • ?A slip loop, not a Kryston
    • ?Inspect step 03

    Then

    • Retie. Do not dress a defective structure and call it seated.
  • Loop closed around the hardware

    Check

    • ?Wrong sequence; action is dead
    • ?Inspect step 02

    Then

    • Retie. Do not dress a defective structure and call it seated.
  • Fluoro substituted for mono

    Check

    • ?This lock is a mono knot — fluoro will not behave
    • ?Inspect step 01

    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 non-slip lure loop must stay open under a straight pull. Collapse means the return path failed — it is a noose, not a tight loop.
  • ·Kreh / Rapala / Homer Rhode families share that job. They are not closed mathematical knots.

What topology does not predict

  • ·Loop size is set when you tie. It is not a crossing number.
  • ·Free-swing is already one of the things Decide weighs. This page does not change it.
  • ·Heavy-leader glaze is material, not topology.

Not for

  • ·A standing mid-line loop or a king-sling-style loop in the line
  • ·Braid-only terminals where the record already rules the family out
  • ·Fluorocarbon
  • ·Anyone who already inspects a Kreh/Rapala more reliably

Same pattern, different job
