Learn to Tie the Blood Knot from The Blue Quill Angler in Evergreen, CO

Used for attaching two pieces of monofilament fishing line together, the blood knot is primarily called upon for rebuilding tapered leaders. When formed properly, the blood knot is exceptionally strong and should be used with two monofilament lines that are close to the same diameter. We recommend using this knot for monofilament fishing line rated at 10 pounds or higher. This is one of those knots that, if you’re not already familiar with it, we recommend practicing before you get in the water since you will most likely find yourself using it regularly throughout your day of fly fishing. The blood knot is typically used with tippet and leader line for a variety of needs from replacing broken leaders to lengthening tippet line that has gotten shorter over the day’s fishing. Follow the steps in the diagram below to learn how to tie the blood knot, then practice it a few times and we’ll see you on the water during your next guided fly fishing trip in Colorado with The Blue Quill Angler.
