Double Uni Knot or Uni to Uni Knot

Double Uni Knot / Uni to Uni Knot

You can join 2 lines of varying or similar strengths with this fishing knot. It is basically tying the uni knotwith 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. It is also known as the double Grinner knot.

Tips

1. If you are not using the swivel, the double uni knot is a good option.
2. Breaking strength is less than 100% but over 90%.
3. It can be used for tying tapered leaders or tippets

Variation

1. Double double uni knot – For joining a braid to a fluoro leader, the former is doubled over before tying the knot.

Advantages	Disadvantages
• Works well • Strong when tied correctly • Quick to tie • Simple • Doesn’t slip or break in most cases	• Not the strongest option for braid to mono and braid to fluoro leader connections. • When tying mono to braid, tends to overstretch the mono.
