OMG
A real safety line knife can be run across your body or skin to cut lines in a panic,try doing that with a normal knife like the one shown,
I totally agree with you regarding the danger of using a real knife in a kitesurfing emergency. But, the knife is inside its plastic sheaf, which is in the harness pocket and when pulled out, the plastic sheaf stays inside the pouch. I always wear gloves and found the traditional Z knife hard to handle, whereas, in practice, I can get a real grip on this knife, plus it is very easy to locate and see. Also, I have this little paranoia of a shark attack after being circled by a white pointer while trying to body-drag back to my board, which was 50 metres upwind. For awhile, I didn't want to go back in the water, but ended up with this knife after discovering that I had lost my fitted line cutter. Maybe I'm kidding myself, but if I ever find myself confronted by a shark again, I feel that I can at least put up a good fight with this, as compared to a single purpose line cutter. In the end, this is my calculated risk carrying this, but overall this sport can also be very dangerous, but we still do it, understanding the inherent dangers.
