Blood Knot
IntermediateLine to Line
A classic knot for joining two lines of similar diameter, twisting each line around the other several times before threading the tag ends back through the middle. It makes a slim, low-profile connection that runs smoothly through rod guides — a mainstay for fly fishing leader building.

How to Tie It
- Overlap the two line ends and twist one around the other 5 times, then pass the tag end back through the gap in the middle.
- Twist the second line around the first 5 times in the opposite direction, then pass its tag end back through the same middle gap from the other side.
- Moisten the knot and pull both standing lines steadily so the wraps compress together, then trim both tag ends.
Best For
- Monofilament
- Fluorocarbon
Tips
- Works best when both lines are close in diameter — for very different thicknesses, an Albright Knot holds up better.
