How to Tie The Double Uni-Knot


This knot is the best for joining braided line with monofilament or fluorocarbon line or leader.


  1. Overlap about 12 inches of the ends of two lines. Form a Uni-Knot circle with the tag end of line "A."

  2. Wrap line "A" five times to form a Uni-Knot around line "B." Snug the knot by gently pulling on both ends of line "A" with enough tension to close the wraps, but not so tight that it actually grips line "B."

  3. Form a new Uni-Knot circle with the tag end of line "B" and wrap line "B" five times to form a Uni-Knot around line "A." (Use only four turns for 60-, 80-, or 100-pound-test monofilament.)

  4. Gently pull line "B" with one hand and line "A" with the other to slide the two Uni-Knots together until they jam--then pull tight. Then tighten the wraps around the standing lines by firmly pulling the tag ends of each Uni-Knot.

  5. Snip the tag ends.
