The Larks Head Knot is an amazingly simple yet useful knot! The great thing about this one is that no matter how tightly it gets stressed while holding all the tension of a flying line, it is fairly easy to remove.
This knot starts with the Loop knot.
Regarding getting this knot loose again, here are a couple of tricks I have discovered from experience...
The lighter the line, the more useful those tips might prove to be! When you need reading glasses, 20 pound Dacron line is pretty hard to work with. Personally, I use eye exercises to improve the situation a lot, but that's another story...
Just about every MBK kite uses a short connecting line between the bridle and the flying line. It's part of the bridle really. The flying line is attached to this connector with a Larks Head Knot, making it easy to swap the line from kite to kite.Now, if you really want to go overboard with knot-tying...
Where else might you use a Lark's Head? Well, I use it to connect the lower bridle lines of the Roller and Dopero kites to their keels. In those cases the knot stays done up all the time. That's because the kites can be packed away after carefully pulling some of the lower bridle lines' length through the slits in the sail.
One more application. I use the Larks Head Knot to attach tensioning lines to the upper and lower horizontal spar bow-lines of the Dowel Sode kite. What a mouthful that was :-) With the 2 bowed spars tensioned away from each other, the kite has a tighter sail and flies much better.
One last point about flying line attachment. For smaller
kites, the Larks Head can be done with a Simple Loop Knot - as in the
illustrative photos at the top of this page. However, you can get a
significantly stronger connection between a flying line and a BIG kite by using a Double Loop or even a Figure Eight Knot instead.
