KnotUse it forStrength / notes
ArborTying line to the reel spoolOnly has to grip the spool, not hold a fish
Improved clinchHook, lure or fly to mono or fluoroThe everyday knot. Wet it and use 5–7 wraps
PalomarHook or lure, especially with braidAmong the strongest. Needs room to pass the hook through the loop
Double surgeon'sJoining two similar lines, adding tippetFast, forgiving, strong
Double uniBraid to mono leader, or mismatched diametersUse 8 wraps on braid
Non-slip loopStreamers, jigs, crankbaitsLets the lure swing freely for more action

Step by step

  1. Arbor knotWrap the line around the spool. Tie an overhand around the standing line, then a second overhand in the tag end, and pull the standing line to cinch it down.
  2. Improved clinchThread the eye, wrap the tag around the standing line 5–7 times, pass it through the small loop at the eye and then back through the big loop. Wet it, tighten, trim.
  3. PalomarDouble 6 inches of line through the eye, tie a loose overhand with the doubled line, pass the hook through the loop, wet it and pull tight.
  4. Double surgeon'sOverlap the two ends about 6 inches, tie an overhand with both lines together, passing them through twice. Pull all four strands evenly.
  5. Double uniOverlap the lines. With each tag in turn, make a loop around both lines and wrap through it 5 times (8 for braid). Snug each, then slide the knots together.
  6. Non-slip loopTie a loose overhand, pass the tag through the eye and back through the overhand, wrap the tag around the standing line 4–5 times, then back through the overhand. Wet and tighten.

Three rules for every knot

Wet it before you tighten, because friction heat weakens monofilament. Pull slowly and steadily. Trim the tag to about 1/8 inch, not flush.

If you only learn two

The improved clinch, to tie things on, and the double surgeon's, to tie lines together. Between them you can rig almost any pond or river setup.
