Double Uni Knot or Uni to Uni Knot
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. It is also known as the double Grinner knot.
