You can join 2 lines of varying or similar strengths with this fishing knot. It is basically tying the uni knot with the line doubled, twice at 2 ends. It is used by both salt and freshwater anglers. When tying braid to mono, make 5+ turns with the mono and 8 turns with the slippery braid. It can unite a fluorocarbon leader with a braided main line and is a good mono to mono knot.
How to tie a Double Uni Knot in 4 easy steps with pictures
- Total Time: 4 minutes
- Materials: Mono Fishing Line and/or Braided Fishing Line
- Tools: Sharp Scissors
Overlap the ends of lines to be joined. Take the end of the line from the left and double back and make 3 to 4 wraps around both lines and through the loop that was formed. Pull tag end to tighten.
Note: When tying mono to braided line, make 5 turns with the mono and 8 turns with the braid.
Repeat with the end of the line on the left making the same number of wraps unless tying with braided line in which you should double the number of wraps.
You have now tied two Uni knots. Pull the standing lines in opposite direction to slide the two knots together.
Clip ends close to the knot.
Double Uni Knot Review
This knot is used by anglers in both salt and fresh water for joining lines of similar or different strengths. Bass fishing legend Roland Martin considers the Double Uni the best knot for tying braided line to a fluorocarbon or monofilament leader. It works well and some find it easier to tie than the Blood Knot. When tying in braided line to mono or fluoro, make 6 to 8 turns with the slippery braided line and 5+ turns with the mono (depending on its thickness – less with heavier line).
