Slim Beauty Knot
For braid → leader, double line → leader, leader → tippet.
A loose double overhand in the leader opened to a figure eight; doubled main line through it, wrapped down and back, loop tucked — a slim beauty.
This card does not say how strong the knot is. A retention figure comes from a bench, in one material, at one diameter, tied by somebody who ties it all day — and the line in your hand is none of those. What it does tell you is whether the thing you have just tied is the thing the record describes.
What this plate is telling you
Leader figure-8 locked with down-and-back braid wraps. Slim diameter-jump join; field-friendlier than FG for many anglers.
Save this as a picture and it works with a dead signal and a nearly dead battery, which is when a joint is most often tied badly. The rest of this page — the steps, the seating sequence, the failure modes and the bench — is for the evening before.
Why this knot
What it earns its place with, what it costs, and what to reach for instead.
- Equal-diameter thin mono joins where a simpler similar-diameter bend is appropriate
- Any version whose wrap count or seating sequence you cannot verify
- Pulling the figure eight tight before the doubled line goes through it
- Threading the doubled main line through only one opening of the figure eight
- Passing the loop through a gap further along the wraps instead of the first gap
- Pulling on the loop, instead of the leader and doubled line, for the final pull
- FG KnotAdvanced

Before you start
- ·Used to tie a leader or tippet to the main line, including braid to a mono or fluorocarbon leader, and a heavy shock tippet to a much thinner line.
- ·Double about 40 to 60 cm (15 to 24 in) of main line, enough for both layers of wraps and the loop.
- ·Leave the figure eight in the leader loose until the doubled line is through it. It is closed onto the main line near the end.
- ·Wrap counts differ between sources, from 4 down and 3 back to 5 to 7 down and 4 to 6 back.

01.1
Tie a double overhand in the leader and leave it open as a loose figure-eight
- Hold:
- Left hand holds the leader standing part
- Move:
- Right hand forms the double overhand and stops before drawing it tight
You should now see: A loose two-opening figure-eight in the leader, with both openings large enough for doubled main line.
Tie a double overhand knot near the end of the leader and pull it only part way, so it opens into a loose figure eight with two open loops.
A loose figure eight in the leader with a clear top opening and bottom opening, each wide enough to take doubled main line.
Pulling the figure eight tight at this point. The openings close, and the doubled main line will not pass through both of them.
Fix: Work the knot open with a fingertip until both openings are clear again, or tie a fresh double overhand.
Why: The figure eight is closed onto the main line later, in step 4. Until then it only needs to hold its shape.

Tying procedure — Slim Beauty Knot
Step 01 / 5
Tie a double overhand knot near the end of the leader and pull it only part way, so it opens into a loose figure eight with two open loops.
You should now see: A loose figure eight in the leader with a clear top opening and bottom opening, each wide enough to take doubled main line.
If it goes wrong: Pulling the figure eight tight at this point. The openings close, and the doubled main line will not pass through both of them.
Fix: Work the knot open with a fingertip until both openings are clear again, or tie a fresh double overhand.
Why: The figure eight is closed onto the main line later, in step 4. Until then it only needs to hold its shape.
Step 1 of 5 · move 1 of 1
Tie a double overhand in the leader and leave it open as a loose figure-eight
Hold: Left hand holds the leader standing part
Move: Right hand forms the double overhand and stops before drawing it tight
You should now see: A loose two-opening figure-eight in the leader, with both openings large enough for doubled main line.
Step 02 / 5
Double about 40 to 60 cm (15 to 24 in) of the main line and pass the loop end through the top and bottom openings of the figure eight.
You should now see: The doubled main line threaded through both openings of the figure eight, with a long loop and plenty of doubled line past the leader knot.
If it goes wrong: Threading through only one opening. The main line lies beside part of the knot instead of through it, and the wraps have nothing to lock against.
Fix: Pull the doubled line back out and pass it through both openings of the figure eight.
Why: Running through both openings lets the figure eight close down and grip the doubled main line in step 4.
Step 2 of 5 · move 1 of 1
Double the main line and pass the bight through both openings of the figure-eight
Hold: Left hand keeps both leader openings clear
Move: Right hand pushes the doubled main line through the first opening and then the second
You should now see: Both legs of the doubled main line pass through both leader openings, with a long bight beyond the knot.
Step 03 / 5
Wrap the doubled main line down the leader, away from the figure eight, 4 to 6 times, then wrap back over those turns toward the figure eight 3 or 4 times.
You should now see: Two layers of doubled-line turns on the leader, the second lying over the first and ending a short way from the figure eight, leaving a small gap.
If it goes wrong: Turns that cross, leave gaps, or split the two legs of the double. You see leader showing between turns, or one leg of the main line riding over the other.
Fix: Unwind to the last clean turn and wrap on from there, pinching the two legs together as you go.
Why: Wrap counts vary between sources. NetKnots gives 4 down and 3 back, Salt Water Sportsman 4 to 6 down and 3 to 4 back, and Cast and Spear 5 to 7 down and 4 to 6 back.
Step 3 of 5 · move 1 of 1
Wrap the doubled line several turns away from the knot, then back toward it
Hold: Left hand pinches the leader and the first turn beside the figure-eight
Move: Right hand carries the doubled bight away from the knot and then back over the first layer
You should now see: Parallel inner turns and an orderly return layer, with the doubled legs staying together.
Step 04 / 5
Pass the loop end of the doubled main line through the first gap, between the figure eight and the wraps. Wet the knot and pull the leader tag against the leader to close the figure eight onto the doubled line.
You should now see: The loop sticking out through the gap beside the figure eight, and the figure eight drawn down small and firm around the doubled main line.
If it goes wrong: Passing the loop through a gap further along the wraps, or leaving the figure eight open. The wraps can slide toward the leader end, and an open figure eight shows as two loose leader loops.
Fix: Pull the loop back out and feed it through the gap right beside the figure eight, then close the figure eight before the final pull.
Why: The loop through the first gap stops the wraps unwinding, and the closed figure eight gives them a firm stop to seat against.
Step 4 of 5 · move 1 of 2
Put the bight through the first gap formed by the wraps, then wet the knot
Hold: Left hand holds the return wraps in place
Move: Right hand pushes the bight through the first gap at the returning wrap layer
Step 4 of 5 · move 2 of 2
Pull the leader tag against the leader to close the figure-eight onto the double
Hold: Left hand holds the doubled main line without pulling its loop
Move: Right hand closes the leader figure-eight around the two main-line legs
You should now see: The leader figure-eight is smaller and firm around the doubled line, with the wrap stack still aligned behind it.
Step 05 / 5
Pull the leader and the doubled main line, not the loop, apart with a fast, steady pull. Cut off the loop and trim the main line tag and the leader tag close.
You should now see: A slim join with the wraps packed against the figure eight, the main line and leader leaving the knot in a straight line, and short tags.
If it goes wrong: Pulling on the loop, or loading one leg of the double harder than the other. The wraps close crooked and the lines leave the knot at an angle.
Fix: Pull only the leader against the doubled main line. If the lines still leave at an angle or wraps have crossed, cut the knot off and tie it again.
Why: The loop is cut off once the knot is seated, so it carries no load. A stiff leader tag trimmed close passes through the rod guides without catching.
Step 5 of 5 · move 1 of 1
Pull leader against doubled main until the wraps seat at the lock and exits align
Hold: Left hand pulls the leader standing part
Move: Right hand pulls both legs of the doubled main line together, not the bight
You should now see: A straight tapered join: leader lock closed, wrap stack gathered against it, and both exits collinear.

Seating sequence — where failures are born
The step list compresses the finish. Run these phases in order, one at a time.
01 Moisten
Wet the structure before any load reaches it.
Zero. Nothing tightens yet.
02 Load
Take up slack slowly until the wraps begin to gather.
Light and even — both ends moving together.
03 Dress
Watch the wraps stack in order; stop and back off if any cross.
Hold, do not pull. Correction happens here or not at all.
04 Set
One continuous pull to full seat — no sawing, no jerks.
Firm, single direction, standing line against the terminal end.
05 Trim
Cut the tag square, leaving a short stub proud of the knot.
None. Never trim under load.

Field notes — dark, cold, gloves
- ·Retie by feel first, light second — the seat is a tactile event, not a visual one.
- ·Gloves off for the dress phase. Fabric hides a crossing wrap.
- ·Wrong twice in a row means the material or the hardware is fighting you. Change one, not your technique.
Slim Beauty Knot — finished-state checks, on the shared reference layout
When this family fails, it fails as these. The recovered end still outranks the name.
Bight in the heavier leader; lighter line wraps the bight, then tucks.
- !Bight in the lighter line — the wraps have nothing to bite
- !Wraps walked off the bight instead of packed against the fold
- !Tag never tucked back through the bight, so the wraps dump
- !Doubled line through only one opening, so the wraps have nothing to lock against
- !Loop passed through a gap further along, so the wraps slide toward the leader end
- !Figure eight left open, so the wraps have no firm stop to seat against
- !Seated by pulling the loop or one leg of the double, so the wraps close crooked

Get it right with everything in your favour0/5 clean
Nothing logged on this knot yet, so it starts on the bottom rung.
Good light, dry hands, a table. Until the sequence is automatic here there is nothing for the harder rungs to test — you would only be learning that difficult conditions are difficult, which you already knew.
How · Tie it, check it against the list, log it. Five clean and the ladder opens.
Nothing marked. Log it clean, or mark what happened first.
Strength, and where the number comes from
Not established
Named by captains in Sport Fishing's braid-to-leader coverage but not among the knots whose break figures were published, so nothing citable carries a number.
Percentages come from published tests on their own line, their own knot-tyer and their own pull rate. Yours is a different system. Treat a figure as a reason to test, not as a result you already have.
