JP, the problem is you're not giving us a good reason why we would ever be out in the woods in the first place, let alone lost. Some might actually enjoy camping out somewhere, but would have better packed survival gear, even on a hike. You could pull out a 'Survivor' type scenario, but even then, the contestants are constantly tracked. Even loggers would have blazed their own trails, so they wouldn't get lost. So, other than getting kidnapped, and escaping, (which means we probably wouldn't have the knife, in this case), whyever would we, as sensible beings, be lost in a forest?
