Based on the square (reef) knot, the surgeon’s knot owes its name to its common use by surgeons to secure the threads in a suture. Though originally a surgical knot it has found wide use in fly fishing to effectively connect the leader to the tippet. It joins 2 lines of equal or unequal diameters as well as lines of different materials.

- It is also referred to as the double surgeon’s knot since it is actually a double overhand knot with the entire leader passed through the knot twice.
- The triple surgeon’s knot utilizes 3 turns for added security. Similarly, it can be given 4, 5 or 6 turns increasing the complexity and bulkiness but adding strength.
