I had a similar idea about the "international waters" issue. Even if it was another country - that doesn't mean the country has an extradition treaty with the US. So, as long as you have a quick way out of the country - you're all set to "win" in a hurry. Unfortunately, I checked the rules of survivor, and they stated that the contestants must obey "all US and local laws." This creates an interesting dillemma - are you supposed to obey all the laws - even the laws that contradict? Is that ALL the different state laws in the US?
As for the survival knife - it wouldn't have to be a sponsorship type thing. The Chris Reeves/Busse/etc. logo wouldn't have to be all over the contestants clothes and such. It could just be a simple free knives/right to say "as seen on survivor" in advertising exchange.
Based on the quality of the contestants, however, I couldn't visualize any sane knife company taking this offer up. The consequences could be serious - contestants could leave the knife in sea water overnight and complain about rust, use it as a prybar/hammer, constantly complain about how their knife won't hold an edge even after repeatedly "re-forging" the knife in a hot fire, or in a worst case scenario - use it as a weapon on national TV and make the manufacturer look really bad/evil to all the sheeple.
Personally, If I manufactured any tool, I would steer a wide path away from ALL reality based TV shows. Hollywood has a real knack for making useful things into illegal things.
Makers of survival tools should continue to sponsor real survivors - Mt. Everest expeditions, explorers, etc. - where their tools can be tested and used under the most extreme conditions, so in the end, we all get better tools, and the manufacturers get a better reputation. The heck with mass acceptance - just give me something that can do the job every time.
