King Sling

King sling loop

Tying a lure, hook or fly to braid or mono with an open loop, so the bait can move more naturally.

Loop · Intermediate · Monofilament / Fluorocarbon · 4 steps

ApplicationsHow to tie it

Finished structure

No drawing of this exact knot yet. The written steps are the reference.

  1. Step 01

    Thread the tag through the eye of the lure and lay it back alongside the standing line, then fold that doubled section back on itself to make a loop.

    No drawing of this exact knot yet. The written steps are the reference.

    You should now see

    A doubled line running back from the eye with a loop folded into it, and enough tag beyond the fold to hold on to.

    If it goes wrong

    Leaving too short a tag. The twists and the pass through the loop use it up, and the tag slips out before the knot closes.

    Fix: Pull more line through the eye before folding the loop, so there is tag to spare after the twists.

    Why: The folded loop becomes the twisted double loop in the next step, and the lure passes through it to lock the twists.

  2. Step 02

    Put an index finger into the end of the loop and turn it counter-clockwise three or four times while your other hand holds the lure and the line.

    No drawing of this exact knot yet. The written steps are the reference.

    You should now see

    Three or four even twists in the doubled line between your finger and the lure, with a double loop around your fingertip.

    If it goes wrong

    Twisting without holding the lure and line, so the twists bunch unevenly or spin back out. The twisted section looks lumpy or unwinds when you pause.

    Fix: Let the twists out, hold the lure and line firmly, and turn the loop again, counting each turn.

    Why: Holding the lure stops the doubled line from spinning, so each turn of the finger puts one even twist into the line.

  3. Step 03

    Pass the hook or lure through the twisted double loop on your finger. If you are tying an open loop with no lure on it, pass the end of the loop through instead.

    No drawing of this exact knot yet. The written steps are the reference.

    You should now see

    The lure all the way through the double loop, with the twisted section held between the double loop and the loop the lure hangs from.

    If it goes wrong

    Passing the lure through only one strand of the double loop, or letting the twists unwind as the lure goes through. The knot pulls out into plain line.

    Fix: Back the lure out, twist the loop again and pass the lure through both strands of the double loop together.

    Why: This pass traps the twists. Without it, pulling on the line only straightens them out.

  4. Step 04

    Wet the knot. Pull the standing line and the tag together in one direction and the lure in the other until the knot closes, then trim the tag.

    No drawing of this exact knot yet. The written steps are the reference.

    You should now see

    A compact knot at the top of an open loop, the lure swinging freely in the loop, and a short tag.

    If it goes wrong

    Pulling on dry line, or leaving the tag out of the pull. The knot closes lopsided and the tag creeps back into it.

    Fix: If the knot is lopsided or the tag has shortened, cut it off and tie it again, holding the tag with the standing line during the pull.

    Why: NetKnots gives it as suitable for fairly heavy monofilament, up to about 50 pound breaking strength. Pulling the tag with the standing line closes both sides of the knot together.

Failure modes

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

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
  • !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
Geometry
  • 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

If you saw this
  • 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.
  • Loop left larger than the system needs

    Check

    • ?Bulk in the guides and a walk-prone eye
    • ?Inspect step 02

    Then

    • Retie. Do not dress a defective structure and call it seated.
  • Used as a free-swing lure loop

    Check

    • ?Wrong job — pick a non-slip terminal
    • ?Inspect step 04

    Then

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