These two knots are critical to your success on the water. Rebuilding your leader is inevitable. You must know these two knots. Notice the info that the blood knot is best for similar sized leader material and the surgeon’s knot is suitable for different sized leader materials that must be joined. I use the surgeon’s knot most often for all my leader construction. Study both and use both. Whether you are standing at the back of your rig, sitting in a drift boat or tube, or standing mid-stream with your rod under your arm and rebuilding your leader….learn these two knots.
