Used to join two lines of similar or different diameters, typically the leader and the tippet. Known for its strength, the J Knot is designed to slide less and hold more securely under tension compared to other knots, using a unique 'double-lock' system.

Step 1

Put two lines parallel to each other

Take the two lines that you're going to use, and keep a significant length parallel to each other.

Step 2

Make a simple knot

Keep the lines parallel and make a simple knot. Keep the loop open.

Step 3

Back through the loop twice

Put the lines back through the loop, and again from the top.

Step 4

Back through the loop from the bottom

Put the lines back through the loop from the bottom one last time.

Step 5

Pull to tighten

Pull on both ends to tighten the knot.
