The Nail Knot

The Nail Knot is the perfect knot for tying backing to your fly line as well as the fly line to the leader and/or the tippet.

Uses: This knot obtained its name after the fact that the originator used a nail as a guide when he threaded his line; today most anglers prefer to use a hollow tube (such as a straw) as a guide.

It is used in the joining of 2 lines with different thicknesses (diameters) as it permits a decreasing of the line diameter all the way down to the fly; for instance when tying backing to your fly line as well as the fly line to the leader and/or the tippet.

Advantages: It is a very smooth and compact fishing knot that will easily pass through fishing rod guides.

Always moisten the Nailknot before pulling it tight.

Place your fly line and the butt section of your leader line next to each other. Pass the leader line over and back under the fly line leaving about 25 – 30cm to make the knot. Place a hollow tube such as a straw next to the fly line and on top of the leader line. (You can also use a nail in place of the straw but a straw works easier). Hold the two lines and the straw in place with your index finger and thumb and then wrap the leader line tightly around the fly line, the straw and the leader line.

Continue to make 6 to 8 tight wraps down the length of the straw working from left to right back around the leader, line and the straw. Now run the tag end through the middle of the straw (or the gap made by the nail) and remove the straw or nail.

Finally pull the tag end to tighten up the coils that you made and then pull the tag end and the leader to seat the knot firmly in place on top of the fly line. Trim the tag end close to the knot to ensure no snags can occur.
