Double Double Uni Knot

Tying procedure — Double Double Uni Knot

1. Step 01 / 4

   Double about 30 cm (12 in) of braid back on itself to make a 15 cm (6 in) double line, then lay the doubled braid alongside the end of the leader, the two ends pointing opposite ways.

   You should now see: Two strands of braid lying together along the leader for about 15 cm (6 in), with the bend of the doubled braid pointing toward the leader's standing part.

   If it goes wrong: The two braid strands drifting apart or twisting around each other, so later wraps go on as single strands. You see a gap open between them.

   Fix: Pinch the doubled braid flat and run it between finger and thumb until both strands lie side by side, then lay it back along the leader.

   Why: Every wrap in step 2 is made with both braid strands together, which is what separates this knot from a basic Double Uni.

   Step 1 of 4 · move 1 of 1

   Double 30 cm of braid into a 15 cm double line and lay it along the leader end

   Hold: Left hand pinches the doubled braid and the leader together

   Move: Right hand folds the braid back on itself and lays the leader end along it

   You should now see: Two braid strands lying together along the leader, the bend of the doubled braid pointing toward the leader's standing part.

2. Step 02 / 4

   Cross the end of the doubled braid back over itself to form a loop, pinching the crossing and the leader together. Pass the doubled end through the loop 8 times around both lines, then pull it to close the wraps.

   You should now see: A neat barrel of 8 doubled-braid wraps snugged down on the leader, each wrap showing two strands side by side.

   If it goes wrong: Wraps crossing over each other, or the two braid strands splitting apart inside a wrap. The barrel looks lumpy and the strands show as separate turns.

   Fix: Loosen the wraps by pushing them back toward the loop, straighten the doubled strands, and pull the doubled end again slowly.

   Why: NetKnots closes this barrel onto the leader before starting the leader side. Once closed it holds its place while you tie the second knot.

   1Eight doubled turns

   Step 2 of 4 · move 1 of 2

   Loop the doubled end back over both lines and pass it through the loop 8 times

   Hold: Left hand pinches the loop's crossing and the leader together

   Move: Right hand takes the doubled end round both lines and through the loop, eight times

3. Step 2 of 4 · move 2 of 2

   Pull the doubled end to close the 8 wraps onto the leader

   Hold: Left hand holds the leader and the braid behind the wraps

   Move: Right hand pulls the doubled end until the wraps close into a barrel

   You should now see: A neat barrel of 8 doubled-braid wraps snugged down on the leader, each wrap showing two strands side by side.

4. Step 03 / 4

   Tie the same knot with the leader tag: form a loop back over both lines, pass the tag through it 5 or 6 times around both lines, and pull the tag to tighten. Use fewer wraps on heavier leader.

   You should now see: A second, shorter barrel of leader wraps closed down a short way from the braid barrel, with a little bare line between the two.

   If it goes wrong: Leaving a barrel only partly tightened. When the knots are pulled together the loose wraps slide unevenly and the tag can draw back through.

   Fix: Pull each tag again until its wraps stop moving before sliding the knots together. If the leader wraps have crossed, undo that knot and tie it again.

   Why: Heavy leader is stiff and does not bed down well over many turns, so the wrap count drops as the leader gets heavier.

   1Five turns of leader (or six)

   Step 3 of 4 · move 1 of 2

   Loop the leader tag back over both lines and pass it through the loop 5 or 6 times

   Hold: Left hand holds the braid barrel and pinches the new loop

   Move: Right hand takes the leader tag round both lines and through the loop, five times (six on light leader)

5. 1Braid barrel

   2Leader barrel

   Step 3 of 4 · move 2 of 2

   Pull the leader tag to close the 5 turns into a second barrel

   Hold: Left hand holds both lines behind the leader turns

   Move: Right hand pulls the leader tag until the turns close up

   You should now see: A second, shorter barrel of leader wraps closed down a short way from the braid barrel, with bare line between the two.

6. Step 04 / 4

   Wet both knots and pull the leader and main line in opposite directions until the two barrels slide together. Trim the leader tag and both braid tags close.

   You should now see: The two barrels butted against each other with no bare line between them, and short tags that do not catch when you run the join through your fingers.

   If it goes wrong: Stopping with a gap between the barrels, or trimming the tags before the final pull. A gap shows as bare line between the two knots.

   Fix: Wet the knots again and keep pulling steadily until they touch. If a barrel slides apart instead, cut the join off and tie it again.

   Why: Pulled together, the two barrels jam against each other. Leaving the tags on until after this pull lets you see that neither knot has slipped.

   Step 4 of 4 · move 1 of 2

   Wet both knots and pull leader and main line apart until the barrels meet

   Hold: Left hand pulls the braid main line

   Move: Right hand pulls the leader the other way, slowly, until the barrels slide together

7. Step 4 of 4 · move 2 of 2

   Trim the leader tag and both braid tags close

   Hold: Left hand holds the join by the main line

   Move: Right hand trims the leader tag, the doubled braid tag and the single braid tag

   You should now see: The two barrels butted together with no bare line between them, and short tags that do not catch when run through your fingers.
