This 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.
To Tie a Double Surgeon’s Loop:
| Double the tag end of the line. Make a single overhand knot in the double line. |  |
| 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 again. |  |
| Hold the loop in your right hand. Hold the tag end and standing line in your left hand. Moisten the knot (don’t use saliva) and pull to tighten. |  |
| Trim off the tag end. |  |
