Surgeon's Knot

Earlier mention was made that if the two lines to be joined vary greatly in their diameters, the lesser line may be doubled at the knot, or the Surgeon's Knot may be used. In the latter case, it will probably be necessary to have one of the lines rolled on a spool, or perhaps wrapped on a temporary card, so that it may be passed through the loop.

1. Lay the two lines against each other, overlapping about 22.5 cm.
2. Working the two lines as one, tie an Overhand Knot. It will be necessary to pull one line (say the leader) completely through this loop.
3. Pull the leader through this loop again.
4. Pass the other end through the loop.
5. The formed knot can now be worked into shape.
