A blood knot is a knot that joins two lines together.

The Blood Knot’s Purpose

The purpose of a blood knot is to keep the line straight and not have any kinks in the fishing line. The other purpose of a blood knot is to make the knot strong. This is done by how many loops are on each side.

Although it looks easy to do with rope, blood knots can become cumbersome when your fingers are cold or with the loss of dexterity.​

How a Blood Knot is Used in Fly Fishing

Blood knots are used in fly fishing because they allow you to make tapered leaders, which are leaders made out of graduated lengths of monofilament. The blood knot helps keep the line straight with no kinks.
