J Knot

The J Knot is considered to be one of the strongest bend knots for tying two lines together, and is often used for tying a main line to a leader or a tippet. While the knot’s breaking strength may be up for debate, its simplicity is clear. The knot is formed essentially by overlapping the main line and leader to create a doubled line, then tying an overhand knot in the doubled line. After that, the leader is passed through the loop in the overhand knot a few times to create the J Knot.
