Step 1:

Take your two line ends and line up parallel over lapping about six inches.

Step 2:

Make a loop with one tag end as shown and pass the tag end at least four times through the loop.

Step 3:

Slowly draw the resulting knot down lubricating it before drawing tight.

Step 4:

Repeat the process with the other line end, remembering to lubricate before you draw down.

Step 5:

You end up with both line ends tied around the body of the other line. Moisten and slowly draw the two main line bodies away from each other so the two knots move together.

Step 6:

Make sure the knot is well bedded down and firm and then trim off the two tag ends.

This knot is probably the best and most effective for joining together two ines of the same or similar diameters. It forms a small neat knot and can be used in an emergency situation when you have been broken off to join your line together again so you can carry on fishing. A reliable knot and another one of those essential basic knots that will prove useful in a wide variety of situations. It is also known as the Running Line Knot and Double Uni-Knot. It maintains a high percentage of the lines strength and should be used for monofilament only. It is not recommended for braided lines. Make sure that once you make enough turns on each side at least 5 to ensure it works effectively.

Line Types

Mono or Mono to Braid


If joining braid to mono, increase the number of turns with the mono to five and make seven with the braid.
