World Fair Knot

Doubled line through the eye, overhand lock seated to the hardware.

• !Eye too small for the doubled pass — the stack never sits
• !Doubled overhand not seated against the eye
• !Tag pulled into the doubled coils so the lock becomes a hinge

• !The tag went under where it should go over, and the knot slides or falls apart when the standing line is pulled
• !The final pass through the new loop was left out, so nothing traps the tag and it can pull back out
• !The folded loop was twisted, so the knot closes into a tangle instead of a lock
• !It was pulled fast and dry, so a crossing rolled over another and the knot set lumpy

• Rolled crossing instead of a folded lock

  The lock opens under load

  World Fair is a folded return through both openings, not a twist · step 04

• Missed one return opening

  Unfinished — crossings will not lock

  Both openings must be taken · step 03

• Used on braid

  This compact fold is a nylon knot

  Braid needs a braid-capable terminal · step 04

• Crossings roll or the lock opens

  Check

  • ?Stacked crossings
  • ?Compact lock at the eye

  Then

  • →Retie wet on mono/fluoro
  • →Do not use on braid

• Finished check failed — Incomplete figure

  Check

  • ?Completed figure geometry seated at the eye
  • ?Tag controlled
  • ?No open segments

  Then

  • →Retie. Incomplete World Fair geometry fails early under tippet loads.

• Rolled crossing instead of a folded lock

  Check

  • ?The lock opens under load
  • ?Inspect step 04

  Then

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

• Missed one return opening

  Check

  • ?Unfinished — crossings will not lock
  • ?Inspect step 03

  Then

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

• Used on braid

  Check

  • ?This compact fold is a nylon knot
  • ?Inspect step 04

  Then

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