The Double Surgeon's Loop is a quick, easy way to tie a loop in the end of a leader. It is often used as part of a leader system because it is relatively strong.
Step 1
Double the tag end of the line. Make a single overhand knot in the double line.
Step 2
Hold the tag end and standing part of the line in your left hand and bring the loop around and insert through the overhand knot.
Step 3
Hold the loop in your right hand. Hold the tag end and standing line in your left hand.
Step 4
Moisten the knot in water and pull to tighten. Trim tag end to about 1/8 inch.
