The blood knot is used for joining two fishing lines together. Popular within the fly fishing community, this joining knot is a great alternative to the double uni knot for those that find it easier to tie.
Use Cases For The Blood Knot
- Attaching leader lines to main fishing line.
- Can be used to attach main line to backing line.
How To Tie A Blood Knot
- Overlap the two ends of fishing line you wish to join together.
- Grab the tag end of one line, and wrap it around the standing end of the other fishing line about 5 or 6 times.
- Take the tag end and tuck it back between where the two fishing lines first meet. At this point, you've just tied a half blood knot!
- Repeat the process with the other end, again tucking the tag end between the two fishing lines, but in the opposite direction.
- Pull the two standing ends to tighten and trim the tag ends close to the knot.
- Congratulations, you've just learned to tie a blood knot!
