What it is for

  • Tying line to a hook, lure, or swivel
  • Joining two lines with a double uni
  • A knot that works with mono, fluorocarbon, and braid

How to tie it

  1. Thread the line through the eye and fold it back alongside the standing line to make a loop, leaving about six inches of tail.
  2. Wrap the tail around both strands of the loop four to six times.
  3. Moisten the knot and pull the tail to snug the wraps together.
  4. Slide the knot down to the eye by pulling the standing line.
  5. Trim the tail.

Tips

  • Use fewer wraps for heavy line and more for light line.
  • Always moisten the line before tightening.

When not to trust it

  • It can slip if the wraps are uneven or too few.
  • Test the knot with a firm pull before you fish.

Field notes

The uni knot's wrapped-loop design grips across different line types. Tied twice, it is also a go-to way to join two lines.
