I have a Dakine harness and did my usual pre-session safety check on my gear and found that my line cutter knife had disappeared from the pocket on my harness. I couldn't immediately get a replacement so considered other options. I found this stainless steel knife at Anaconda and it seemed perfect for what I wanted, and even though I was was prepared to pay much more, this fitted the bill perfectly for what I wanted, for less than $4! It has a locking sheaf, a line cutter and the knife itself is extremely sharp and stainless steel. I removed the spreader padding strip and rotated 180 degrees so that the knife pocket was on top. The knife fits in securely with only the handle protruding, but I may fit a small velcro strip over it just to insure that it can't come out unintentionally. I have been on the water five times already and it hasn't moved. I may also attach a line to the handle as well.

That looks a bit drastic, at least you will be well protected if you get mugged out on the water 
I fitted one of these 7 Hook Benchmade Safety Cutters to my harness a few dwinders ago, just using the pouch it comes with. So far I have not needed a knife in my 7 years of kiting but you never know.... if I do, I gonna want something sharp.
No guarantee that I'll be able to find it in an emergency but at least its there if I can.

Andy, I totally agree with you! I always wear sailing gloves and it was not easy getting to the concealed linecutter where it was located on the harness. Maybe this could be a better alternative and easier to get to because of the handle? Also, if something with big teeth decides to take an interest in you for lunch, while body dragging, maybe you would have a fighting chance! 
Not sure about this option "coastflyer".
I have been in situations more than once were either my lines, or others have been wrapped around many parts of my body and I wouldnt want to pull
a standard dive knife across my bodyand hope to ONLY cut the lines, so a line cutting knife which is more expensive maybe is the only one that can be used and dragged against your skin and cut lines only.
You can drag a line cutting knife across your skin were lines are tangled and it will only cut the lines.
forget the dive knife! who is going to try cut lines tangled around there throat while being dragged underwater.
The negatives for the dive knife option is really evident so this is why you never see it.
Very good point Surfguy, I hadn't thought about the lines wrapped around the body situation too much and the mechanics of actually using this knife.. Cost was never a consideration, but I saw this and it appeared to fit my requirement. Other than turning the spreader padding upside down, I haven't had to modify the harness in any way. The 7 Hook Benchmade Safety Cutter as shown above looks like a really good option, so I think I will order one of those. Also I will keep the knife pouch on top as you can look down and see it, as compared to feeling for it in the standard setup. This is why I run ideas like this on here because it draws on other peoples experience! Just wondering, has anybody on the forum had to use a knife in anger while kitesurfing?Select to expand quotesurfguy said..

You need a proper knife scabbard that you can strap onto your thigh.
To make it safer, snap the tip off and round it to a butter knife profile. That the style some emergency services use for working close to the body, eg cutting seat belts. Less chance of stabbing yourself or your kite.
Why don't you just buy a $20 hook knife off ebay? Plastic cover safe to use, will prob fit in your harness pouch too
Whilst the big knife seems a bit OTT great idea flipping the spreader bar pad so the hook knife is easily accessible and also is at the front of your mind as you always see it. Also less chance of loosing it from falling out. I've had a couple of potential kitemares with lines wrapped around me and in the heat didn't think to use the knife. Cheers coastflyer.
The one time I needed a hook knife - to cut the line of a ****ing fisher**** buoy - I discovered the knife was gone from the spreader bar pocket 
cost me a board, that did.
Hook knife or no knife imo.
Ur dealing with a high impact sport and u wanna carry a blade around?

or grind the tip off
Looks like a rescue knife, hook knife and window punch at the top and the blade is for cutting through shattered glass and window tint. The blade isn't ideal for cutting under tight seatbelts or something like tightlines because you Hav to slide it under flat and twist before you can get the sharp edge working. Go a proper hook knife, ya can't cut yourself and simple one handed operation.
I made a leash for my hook knife out of old kite lines and I coil it up in the sleeve of the hook knife. This way if you grab it and it slips out of your hand in the surf or whatever, you can still retrieve it and have another go. When things go bad it is rarely a straightforward process to make yourself safe. The idea of losing a knife just within reach would not be good. As someone else once mentioned on this forum, keep the knife covered in wax and it won't rust and stay sharp. That was really good advice.

It was only to show what a blunt nose knife looks like, not to go buy one!
And anyway, the seat belt cutter is the tiny blade up the top.
Hook knife. Designed for the purpose. Provided by the manufacturer. Harness has a holder for it. Relatively cheap and reliable.
I have needed a hook knife once in 14 years of kiting when riding out a 65 knot squall (from a nearby weather station. Probably only 40-50 knots where I was.) A couple of lines got wrapped around my foot. I was not about to dick around with the lines or wait and see what happened. I pulled the knife out, cut the lines, the kite rolled over and settled in the shore break. End of problem. Spent the rest of the weekend riding the kite with a bar from another kite and bought some replacement lines after the weekend.

Gorgo, thanks for sharing. I'm going to order one of the Benchmade cutters as shown above. Keep it simple and safe!
Same thing happened to me - was checking my harness and found the hook knife had fallen out. I went and bought a new Dakine hook knife for about $25 from my local store, then secured it to the harness with a length of thin bungy cord from the hardware store. I made sure that the bungy cord was able to stretch to the full length of my reach, and it just stuffs in the knife pouch. I chose bungy cord because I didnt want it attached to a long cord that could potentially add to a tangle in a bad situation.
The added bonus is that the added bulk of the bungy cord in the pocket holds the knife in alot better. It hasnt fallen out once since installing it but is still accessible when you need it. Great idea flipping it over so you can get it from the top though, might try that myself!
I'm think something like this would be ideal, and at $10.

Better to use a kitesurf specific knife. They come with a bit built-in piece of velcro to hold the knife into the harness pocket. Mystic knives are good and cheap enough at $20. So are Cabrinha or Dakine. Buy them in the internet.

Rinse it and dry it whenever you remember. They get a little corrosion on the base of the blade where water pools against the frame. That won't stop the knife from cutting kite lines.

Why not just buy a $10 purpose built line (hook) knife from your local kite shop. ??
Less than $20 complete with the pouch to attach to your harness straps.
I think that looks really dangerous to be honest, anything with a point and a blade more than a couple of inches long is going to cause some serious damage. You would be better off getting a proper kite knife or at least as someone else said round off the point so you don't end up sticking yourself with it.
Looks dangerous to me. That is a lot of blade with a very sharp point which could be hazardous (only has to happen once). Plus it would not be nearly as effective for cutting lines as a line knife with the hook to guide lines to the protected blade.
PS: Why is your Donkey Dick so long? It looks huge.
