Surgeon's Knot 1. Lay line and leader parallel, overlapping 6" to 8". 2. Treating the two like a single line, tie an overhand knot, pulling the entire leader through the loop. 3. Leaving the loop of the overhand open, pull both tag end of line and leader through again. 4. Hold both lines and both ends to pull knot tight. Clip ends close to avoid foul-up in rod guides.
