Line Mending Knots

For Kite Flyers, Illustrated

A number of line mending knots are illustrated here, although you'll probably end up picking just 1. It all depends what you care about. Super quick and simple? Ultimate strength? Or something in between that just appeals for some reason?

Having done some testing on old but unused line of various weights, I have been able to list the methods in order of strength. Only by tying them yourself will you discover which might be the best for you.

Personally, I was impressed with the high strength and rather neat appearance of the Blood knot. However, I'm currently going with my own invention: the Triple Granny :-) since it's so much easier to tie!

Multi-Strand Double Knot

1. Start side-by-side
2. Loop around and cross over
3. Around and through once...
4. Around and through again
5. While loose, work towards ends
6. Pull tight

This is also referred to as a double overhand knot. The Multi Strand Double Knot is rather handy for line-mending, although my tests found that it weakened 20 pound line by about half :-|  For 100 pound line, it did better. Although ugly to look at, it's so easy to do, and that extra turn of line makes it slip-proof. Unlike the a simple overhand knot when connecting 2 lines!

If you are prototyping a new kite and need to quickly add in more length to a bridle line, then this knot is a quick-n-dirty way of doing it. The reduced strength is not so much of a concern in a bridle since the strain is shared between 2 or more lines.

Apart from modifying a bridle, this also came in handy for me once when scrapping and old sail and re-using the horizontal spar(s). The old bridle lines were snipped so they could be fed through holes in the new sail.



Fisherman's Knot

1. Left over right
2. Around the back
3. Simple overhand knot
4. Pull end tight
5. Take other end behind
6. Up and around
7. Behind and through
8. Pull end tight
9. Pull lines apart, bringing knots closer
10. Pull knots together

Also known as the Fisherman' Bend, Angler's knot, English knot and a few others!

The Fisherman's knot, despite looking complex when done, is actually composed of 2 simple overhand knots. Hence it is quite easy to remember how to tie. For mending your flying line, it looks neater and is slightly stronger than the Multi-Strand Double knot.

The Double, Triple and even Quadruple Fisherman's knot variants are stronger but not as easy to tie properly. They are not covered here, since I have to draw the line somewhere. There are so many knots out there!




Triple Granny Knot

1. Cross left over right
2. Around the back
3. Around twice more
4. Again, cross left over right
5. Around the back
6. Around twice more
7. Tighten, pulling all 4 strands
8. Drop short ends, tighten further

There's a chance I might not have been the first person to ever tie this, but perhaps I'm the first to name it. And therefore to claim it as the Triple Granny :-) 

This knot did quite well in a bunch of pull-tests, and will now be my preferred means of joining 2 lines together. Or will be, the next time I spot a bad fray! Snip and fix. In actual fact, breaking a flying line in flight is fairly rare for most of us. Joining lines is more likely when trying to get a super-long length to fly on. Or, as just mentioned, fixing bad frays before they do the inevitable. Another situation is when you've put a complex bridle together for a large kite and realize that 1 of the lines needs to be quite a bit longer! Snip, tie, tie, done.



Blood Knot

1. Left end over right
2. Round the back
3. Around twice more
4. Left and through
5. Other end down and over
6. Around the back
7. Around twice more
8. Through middle, opposite direction
9. Tighten in 3 directions
Drop short ends, tighten further

For most casual kite flyers, I think this would be the King of line mending knots! A little tricky to tie, especially with line weights under 200 pounds, but it creates a connection of great strength.

For simplicity, I have demonstrated a knot with just 3 turns on either side. However, if you add more turns, the strength can approach 100% of the line's un-knotted breaking strain! Fishermen use up to 8 turns each way, on slippery fishing line. However, I think braided Nylon or Dacron would achieve similar strength on just 4 or 5 turns each way.




I trust that you will find a satisfying way to connect lengths of kite line from this selection of line mending knots. That is, something you find convenient to remember and tie out in the field. All the knots here will hold fast, don't you worry about that :-)
