If there’s only one knot you master in your fly fishing journey, let it be the uni knot. This versatile, robust knot can save your day on the water, whether you’re tying two lines together, securing your hook, or creating a loop connection.

Named after its creator, Norman Duncan, the uni knot, also known as the Duncan loop, was born in the 1960s. Since then, it has proven itself indispensable in the world of fly fishing.

Let’s dive into the steps to tying a single uni knot to a hook, and later, we’ll explore how to craft a loop and a double uni knot.

How To Tie A Uni Knot

Step 1

Start by threading the tag end of your line through the eye of your hook. Pull about 6 inches down the main line, then fold the tag end towards the eye of the hook. This creates a loop and a double main line. The loop is crucial in this knot; without it, it simply won’t work.

Step 2

Next, wrap the tag end around the double main line, within the loop you just created. Ensure you’re working through the loop, not over it. Six or seven turns should do the trick. When you finish, the end of the tag should exit from the main loop.

Step 3

Moisten the knot, then pull the tag line to close the knot around the main line. Slide it to the eye of your hook and tighten it down. Now, you can trim the ends of the line. Congratulations, you’ve just tied a Uni knot!

Step 4

If you wish to create a loop with the uni knot, simply tighten it against the leader line at your desired loop size instead of sliding it all the way down to the hook.
