Surgeon’s Knot

How to tie the Surgeon's Knot. This knot ranks as one of the best and easiest to tie knots for joining lines of equal or unequal diameters. It can also be used to join lines of different materials. It is simply two overhand knots with the entire leader pulled through the knot each time. When properly tied, the Surgeon’s Knot approaches 100-percent line strength. It must be tightened by pulling on all four strands to properly seat the knot.

To tie the Triple Surgeon's Knot, proceed to do a total of three (hence the triple in the name) wraps of the loop through the overhand knot. There is some measure of added security with the Triple Surgeon's, but the knot does get a bit bulky.The Surgeon's Knot is one of 12 great fishing knots included on the Pro-Knot Fishing Knot Cards (click to see).
