Discounting the sense in trying to repair cut kite lines, what knot works that can be relied on to stay put? A granny knot with a couple of half hitches certainly did no work and came undone as soon as there was decent load on the lines. Was after a simple knot that could be replicated on all four lines leaving them all relatively the same length. In hindisght I now think a fishermans knot might have been the way to go. What knots have been found to work?
Didn't realise that was possible. But I now see what you mean. I now see the line is hollow so I could have spliced it back into itself if I had an awl in my pocket. Then stitch to secure. I think it would have been too time consuming and difficult in the circumstances I found myself in.
I had all 5 lines cut and needed a quick repair to sail a mere 200 metres back upwind to avoid a 20km round trip home by land. My repairs failed so I had to take the long way home
Was really just after a quick and dirty repair to get home.
I've got nothing to offer on the knots, but I have to ask, how did you manage to slice through your lines?
for ease and reliabilty i would have done bowline in every end easy to replicate so u get all lines the same lenght and wont come undone , as a quick fix only, im sure there would be a more permanent fix 
Unless you got q power line for lines you can't successfully tie any sort of knots in kite lines , they will fail .you could probably get away with a bowline to get you home but as soon as you get back to the beach that would be the end of that line.
There's a kit you can buy to resplice lines to get you out of trouble , I hear they work great.

The binimi twist is a 100% knot strenth,when done correctly, used by big game fishermen, I've a mate that takes punters on $1000 a day fishing gigs, if this knot fails the punter gets his gig for free, it must be pretty strong
I wouldn't trust any knot but if you were going to have a go then fishing knots would be the way to go.
The Bimini Twist is a great knot but takes a bit of practice to get right and whilst the arguably best knot for attaching hooks etc, I'm not sure how you would go tying two lines together.http://www.5min.com/Video/How-to-tie-a-Bimini-Twist-51026687
I mainly use a Uni Knot for fishing, it is still a great knot but is a bit easier to get right and I think would be better/best for attaching two lines together.

Bimini twist is mainly used to tie a double line then the double is tied to a snap swivel so that when you use a conventional knot to tie the snap swivel it doesn't make the knot the weakest part. Bimini twist wouldn't be very easy with kite lines, alot easier with nylon fishing line.
Why would you use a bowline or a bimini twist? They are both connecting loop to loop knots. That's going to make a load point on the line where the two loops connect. The line will fail at that point.
A double fisherman is going to join the lines with no load point except for the knot itself.
Alternately, if you could :
- tie a figure 8 knot in one broken end.
- larks head the other broken end onto the knot with a hitch and a stopper knot.
Depending on which lines you have broken and how your kite is rigged, you could scavenge one of the adjuster pig tails off the end of one of your lines and use that as a temporary connector. You're going to want to adjust the unbroken side to match the shortened knotted side. (I might go home and stuff a short length of spectra into my hook knife pocket or some other out of the way place on my harness).
it will be or hassle then its worth.
the lines will stretch all different and fly funny and if it breaks or comes undone at see your in trouble.
just buy some new ones.
cabrinha was giving out replacement lines last year, I'm sure a shop will sell you a spare pair.
This is the knot I used, and I've used it several times.
It does weaken the line but it will get you home. This animation is good, but instead of only going around both lines once, go round at least 4 times, on each side.

This is the only knot I have ever known to work on slippery Spectra lines (unlike ropes etc). The blood knot:

It's actually easier to tie than the diagram shows!! Basically you just twist the lines around each other, make a centre parting, poke one line UP through the gap and the other line DOWN. Then pull tight.
just tie a knot in one end maybe 2 together to increase size. then a simple loop (double over and tie) then use loop as a larks head knot over the other end knot.
