You’re only as strong as the weakest link in your tackle.

Surgeon’s Knot

This knot is used to join two pieces of line. When properly tied, the Surgeon’s Knot approaches 100% line strength, making it a knot to have in your repertoire!

Without doubt, it’s one of the easiest & best knots for joining lines, whether they’re of equal or unequal diameters, or of different materials. It is simply two overhand knots with the entire leader pulled through the knot each time. Of course, this excludes the Surgeon’s Knot as a mid-line jointer. It’s used for creating short extensions, such as standard or tapered leaders.

NOTE: It must be tightened by pulling on all four strands to properly seat the knot.

Step One
Lay the two pieces of line to be joined on top of one another overlapping each other by several inches.
Step Two

With both lines together, form a simple loop.

Step Three

Pass both the tag end and the entire leader through the loop twice.

*As an option, you can pass both tag end and leader through the loop an additional time to tie the ‘Triple Surgeon’s Knot’. This may add further to strength, but it will increase bulk in your knot.

Step Four
Moisten knot and pull all 4 ends tight.

REMEMBER: This knot must be tightened by all four strands at once to properly seat it.

Step Five

Trim mono or flourocarbon lines as close to the knot as possible, without nicking the knot. Any excess line here has an annoying habit of catching on runners and hampering your cast. With braid, you can leave a few millimetres of tag, as it is soft and will not catch. This allows for a little bit of “slip”.
