When trying to connect one line to another, particularly braided to monofilament line, the double uni knot can be a reliable option for fishermen. Also called the “back-to-back knot,” the double uni knot is a joining knot that is simple, sturdy and easy to learn. DICK’S Sporting Goods Associate and fishing enthusiast Justin Lonchar outlines the quick steps to achieve this strong fishing knot.

STEP-BY-STEP INSTRUCTION

  1. Take the two tag ends of your line and lay them over one another.
  2. Pinch the two lines in the middle.
  3. Create a loop with the one tag end and wrap the tag through five times.
  4. Moisten the fishing line and pull tight. “The wrap should be nice and even, creating a raised knot,” Lonchar says.
  5. Repeat the process with the remaining tag end.
  6. Once you have the two raised knots completed, pull the main lines so the knots come together.
  7. Secure the knots tightly and trim your tag ends.

The double uni knot can help you join a monofilament leader to a braided spool or help you attach your main line to backing with ease. Use these tips and tie into more fishing fun with the double uni knot.
