King Sling

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

King Sling — finished-state checks, on the shared reference layout
When this family fails, it fails as these. The recovered end still outranks the name.
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
- !Lure passed through one strand of the double loop, so the knot pulls out into plain line
- !Twists unwound before the lure goes through, so the pass has nothing to trap
- !Closed dry or without the tag in the pull, so it sits lopsided and the tag creeps back in
Wrong loop order
A slip loop, not a King Sling
Order is the lock on this doubled-line loop · step 01
Loop left larger than the system needs
Bulk in the guides and a walk-prone eye
This is a system loop, not a free-swing lure loop · step 02
Used as a free-swing lure loop
Wrong job — pick a non-slip terminal
King Sling is a doubled-line eye, not a Rapala · step 04
Loop slips or collapses
Check
- ?Loop stability under pull
Then
- →Retie
- →Use Perfection Loop as alternate
Finished check failed — Loop closes to the eye
Check
- ?Fixed loop geometry preserved
- ?Wraps ordered
- ?Loop action free at the lure
Then
- →Retie. Closed loop removes the free-swing action the knot is for.
Wrong loop order
Check
- ?A slip loop, not a King Sling
- ?Inspect step 01
Then
- →Retie. Do not dress a defective structure and call it seated.

Same failure class, different geometry. Open the plates — Diagnose still starts from the symptom.
What holds it
- ·A fixed loop is a standing eye. The collar or figure-eight body must survive a straight pull without becoming a noose.
- ·Bowline and sheet bend are the same crossing pattern under different load. That identity is seamanship, not a reason for Decide to swap one for the other.
What topology does not predict
- ·Fixed vs slipped is a load-path question. Invariants do not choose bowline over figure-eight.
- ·Ring-loading and slack-shaking failure are physical. Topology does not grade them.
- ·No UIAA or manufacturer number is inferred here.
Not for
- ·A lure that must swing on a non-slip loop — this standing eye is a different job
- ·Letting a climbing identity pick your fishing knot
- ·Free-swing lure action (prefer non-slip lure loops)
- ·Braid-only terminals and heavy shock leaders
Same pattern, different job
No sourced twin among these knots. Related knots stay on the Library card.
- Bowline — seamanship identity with the sheet bend (Wikipedia) — Standard identity: bowline is the sheet-bend tangle with the loop loaded.
- Knot — practical vs mathematical (Wikipedia) — Closed-curve knot theory ignores friction. Practical knots are classified by function.
