The Double Uni Knot Is Ideal for Fresh Water and Salt Water Anglers

The Double Uni-Knot can be a difficult knot to master and it can be a bit repetitive so it takes a great deal of careful attention to detail as you work through the knot. It helps to go slowly and to take your time in doing the steps correctly until you have really mastered the art of this particular knot. 

The Double Uni Knot is used by anglers of salt and fresh water fish. It is the ideal knot for joining lines together that are similar or different strengths. 
 
Step 1:
 
In order to create the Double Uni Knot you need to overlap the ends of two lines for roughly 6 inches in length. Make sure that the lines are similar in diameter.

Step 2:
Then you need to tie a loose knot (uni) before making six full turns around the towlines. Make sure that you leave the loop open.
Step 3:
 
 
Then you need to tie a loose knot (uni) before making six full turns around the towlines. Make sure that you leave the loop open. Now you can feed the tag end through the open loop before pulling it through to form a tight knot around the line.
 
Now you are ready to repeat steps one through three in the exact same order. this will ensure that a snug knot will form on the other line. Next you need to cinch up both knots by pulling the two standing lines in opposite directions in order to effectively slide the knots together tightly. The last thing you need to do in order to form your Double Uni Knot is to trim the ends close to the nearest knot and then you have completed all of the necessary steps.

Our Take:

When working on your knot, make sure to leave yourself plenty of line to work with as this will make it much easier to form your Double Uni Knot. You can even use trick that the old pros use and use Chap Stick on your line to keep it moist and pliable.
 

A “Double Uni Knot” is just as the name says, it is the act of tying together two of the Uni Knots to create one. Its purpose is to improve the fishing knot’s hold and knot strength. 


Which is precisely what it does.


The breaking strength of the Double Uni Knot is well over 90% and just under 100%. But it is not the easiest knot-tying experience. Nonetheless, many Fishermen and women consider the knot to be easier to tie than the Blood Knot and just as reliable. 


If you are not using the swivel, the Double Uni is a great knot option. It is perfect for tying tapered leaders or tippets material. The Double Uni Knot is ideal for freshwater and saltwater anglers. 

Double Uni Knot Fishing Tip

Although the Double Uni Knot can be a challenge to master, there are a few fishing tips you can use to make it less challenging to tie. 


Knot Tying Instructions:


  • Pay close and careful attention to detail as you work through the knot. 
  • Go slowly and take your time to do the steps correctly.
  • To master the art of this knot, it will take a lot of practice, but it is worth it.
  • When working on your knot, leave yourself with plenty of the main lines.

Some anglers consider the Double Uni the best knot for tying braided lines to a fluorocarbon or monofilament leader.

How to Tie a Double Uni Knot

  1. To form the Double Uni Knot, it requires the joining of two fishing lines, particularly those of different diameters and material. The intention is to create one secure connection. Be sure to leave enough overlapping lines (about 5 to 6-inches) to make several wraps.

  1. Take the tag end of the line from the left and double back to make four wraps around both lines (if using braided line, double the number of wraps from four to eight to ensure strength), and then run the tag end through the loop.

  1. Repeat with the end of the line on the left, making the same number of wraps unless tying braid line in which you should double the number of coils.

  1. You have now tied two uni knots. Just pull the standing lines in the opposite direction so that the two knots slide together (remember to moisten your knots before tightening to prevent line damage caused by friction).

  1. Trim the ends of the line close to the knot, and that's it. 

You have just tied a Double Uni Knot.
