How to tie a Uni Knot

This is a very versatile knot. A small loop can be left when fishing with a swimming plug to allow the lure greater action, two Uni knots can be used to join line, or the Uni knot can be formed around the hook shank to quickly snell a hook. If you don’t have time to learn any other knot, learn this one. Use to Tie fly to tippet. Creates a sliding loop that can be left open or tightened against hook eye. The open loop on this knot lets nymphs and other subsurface flies “swim” in the water and bass bugs pop better.

The Uni Knot is a good alternative to the Improved Clinch. It is very reliable and very easy to tie. This is a good knot when it is getting dark or if your eye sight is less than perfect!

How to tie a Uni Knot

  1. Take the end of your line and pass it through the eye of your terminal tackle, allowing about 6 inches of line after the eye. Double your line about three inches to make two parallel lines, then form a loop below the doubled lines.
  2. Take the tag end of the line and pass it over the two pieces of line and back through the loop six to eight times. Snug up turns by carefully pulling the tag end.
  3. This knot can be used two ways, depending on the presentation you want and the terminal tackle you are using. It can be cinched up tight to the eye or left above the eye to allow the terminal tackle to move freely. When a strike occurs, the knot will tighten down from the pressure. Either way, be sure the knot is solid and don’t forget to trim the tag end.
