The J Knot is probably one of the strongest knots for the scarf. It starts out similar to the Surgeon's Tie, but the wraps are changed, which puts less pressure on the strings. The J Knot has been tested to be slightly stronger than the Surgeon's Knot, the Blood Knot, and the Double Uni Knot. All are good leader nodes for joining the leader to the line. The J Knot has been proven to be the strongest line tie knot. The J Knot is considered one of the strongest knots for tying two ropes together and is often used to tie a main rope to a leader or a tippet. While the breaking strength of the knot is debatable, its simplicity is obvious. The knot is essentially created by overlapping the main line and leader to create a double line, and then tying an overhand knot in the double line. The leader is then passed through the loop in the upper knot several times to form the J Knot.
How to Tie the J Knot?
Put the ends of the labels through the lines, a few inches parallel to each other.
Holding both strands, tie a simple overhand knot by pulling the entire leader to complete the knot.
Take all the leader and tag end of your main line and loop them again.
Put the leader and tag end through the knot once more and pull the leader and tag end completely through the knot.
Moisten and pull all threads at the same time to tighten the knot.
