Double Larks Head Knot

The following is a knot I use for attaching kite lines to reels and spars. The advantage is that the line will tighten around the reel but will not slip around or fall off when the line tension is released. But the knot is still easy to undo and can be removed like a normal larks head to leave the normal loop in the end of the line.

This knot should be added to the Kite Flyer's Knot Gallery.

Construction

This knot is created by making a normal larks head knot then using the loop created, do another larks head. Tighting the first larks head to the string itself to make a noose which does not slip so much.

You start with a normal loop in the end of the line as you would for a normal larks head knot.

                             ,.
       _______________       ||
                      \      ||
               ---->   | --> ||   ---->
                      /      ||
                     /       ||
                    |        @'
                     \______/`

Pull some of the line though the loop to make a larks head knot OR sometimes called a slip knot/loop if the larks head is not tighened, as you would if you were going to thing insert a second line with a stopper knot on the end (AKA photo 1)

                               __
       _______________        /  \ ,
                      \      |   ,@
               ---->   | --> |   ||   ---->
                      /      |   ||
                     /       |  //
                    |      -===''
                     \______/ 

Using the just created (slip) loop (the unclosed larks head knot) use that to pull more of the line though it as if you were making a second larks head with the first. Now tighten the first larks head knot onto the line itself. You will end up looking like the photo above.

The result is a slip knot which is suitable for attaching a kite line to a thick spar, rod, handle, or fishing reels. It will stay put and not slide off or slip around the object when you start winding line onto it as a normal slip knot or larks head would around a thick object (expecally the glass bottle).
