Oh, the "Basic Mora" I'm talking about costs 2 € - they are bulk stuff =) Very sharp and good enough for all general purpose work. The downside is that the blade is made of such a metal that it is not easy to sharpen once it gets dull. So, for serious survivalist needs I would choose one which is easy to sharpen.

Other than that, I guess it is question of how much equipment one wants to carry. I'd prefer a basic knife, an axe, a sharpener, and a separate striking iron for starting a fire.
