The Larks Head knot is perhaps the only knot a kiter needs to know, and is certainly the most used knot in power kiting.  It is used to attach both ends of flying lines to the kite bridles and handles.

It looks very simply, and unlikely to hold.  However it is slip knot, and so the harder its pulled the tighter it becomes.  You just have to learn to trust the Larks Head, we've never seen one come undone under tension.  But as pressure is released the knot is very simple to undo after flying.

If you have not tied a larkshead before, practice these steps in front of the telly before setting off for the flying field.

1/ Insert thumb and forefinger through the sleeving loop in the end of the flying line, and spread them apart.

2/ Bring your wrist over the top of the lines to form two loops round the thumb and forefinger.

3/ Pinch the thumb and forefinger together to trap the two loops.

4/ Remove your fingers, and pinch the two loops you have just formed together.

5/ Inset the leader for the handle or bridle through the two loops.

6/ Pull tight. and slide down to seat against the knot. Job done.

With a bit of practice you can tie this knot in a couple of seconds, and so long as its pulled tight it should never let you down.
