It is very likely that the most substantial tippet to tippet knot is the J Knot. In creating this knot, the way it is supposed to be started, is very much like the Surgeon’s Knot, except alternate wrapping is required. When wraps alternate, it is thought to put less on each line. In tests performed by Field and Stream, results indicated that the J Knot’s strength surpasses the individual strengths of the Surgeon’s Knot, the Blood Knot as well as the Double Uni Knot. All these Knots are great options for attaching a leader to fishing line. Yellowstone Angler further strengthens the J Knot’s credibility by stating that their results indicate that it is the most powerful line connection knot. The details of this claim can be conferred in their all-encompassing "Tippet Shootout" article.

 

In order to tie a successful J Knot, follow these instructions:

 

Place the main line as well as the leader in a parallel fashion (so that the two lines are alongside each other) while overlapping each line with several inches that will be free. It is important that you keep in mind that the leader and the line should not be the same length, and the knot that is tied is the size needed to tie the know and the leader will be as long as the leader you wish to tie on.

 

Create your first loop by trying a standard overhand knot and make sure to pull the leader in its entirety through the loop.

Take the end of the line and all the leader through the loop from the back of the loop you just made.

This process needs to be repeated from the back part of the loop, taking it to the front side and once more, the process must be repeated from the bottom part of the loop.

Before you pull the lines to tighten the knot, make sure you moisten the lines with water – with this done, firmly pull the opposite sides of the lines tight.
