I know that a lot of you are strictly fixed blade users, and if you have a folder it's probably a SAK or a multitool, but I'm interested to hear which folding knives you depend on in the wilderness. Paired with a fixed blade, or by themselves.
It's an interesting question that depends entirely on where you go, what you're trying to do, what else you bring in terms of equipment and what techniques you use.
I've concluded that my minimum requirement for wilderness travel is a small pliers based tool like the Leatherman PS4. In most (but not quite all) conditions, I consider everything beyond that a fun luxury that I literally weigh against pack weight.
In a mountaineering context (which is a form of wilderness), cutting wood for warmth or shelter and eating off the land just aren't practical. So, one relies on tents or tarps, stoves, packed in food and sleep/clothing systems. Essentially, leave no trace backpacking and ultra light backpacking take the same basic approach only pared down to the bare minimum. Obviously, this may not be everybody's cup of tea, but it proves the point that one can safely move through the wilderness without harvesting plants and animals.
I typically carry a light folder, most often an Opinel. It's primarily for food prep.

Occasionally I carry an Emberlit stove as a back up. I do this on light XC ski tours and on backpacking/hiking with larger groups. I'll carry a fixed blade, usually a Mora Companion, and sometimes a folding Silky saw.
