I usually carry whatever is locally available and fairly cheap. I prefer carbon steel over stainless as most tend to be sharper, easier to sharpen and higher quality but that's not the case with some of the European stainless blades I have seen.
However, when I'm in Canada I always pick up a Mora Swedish carbon steel knife (the basic model with the red birch wood handle) when I have a chance. They are only about 10 bucks and are about the most useful and sharp knife to have around in the bush. I would recommend them over most others...I would rather spend 100 bucks on hunting equipment or horse tack than an expensive knife that won't be any more durable or cut any better...A buddy of mine gave me an Opinel as a gift several months ago when we hooked up overseas and I thought it was kind of neat at first but it broke shortly after while doing meat-cutting/chopping duty, they don't seem to be that sturdy for anything but light work. Right now I am just carrying local Ecuadorian cheap-o knives but they work well enough...
