What tasks is a knife likely to be needed to perform?

I understand some might need to dress an elk, but I'm not a hunter and if I was lost in the wilderness I probably wouldn't have a gun to shoot one to dress. Any of my knives could gut a stream fish.

I got the knife bug a couple years ago (in no small part because of ETS -- cha-ching!$!$!) so now have most of the Ritter stable (Mk-1, mini, 3, 4 and 5), a few Bark River and some other folders.

It's the "other folders" that I rely on during car camping where the major knife tasks are cutting tent rope and opening firewood bags.

The Barkies have very thick blades. The Ritters less so. The Moras even less. All are sharp as heck. As I consider which to carry, when and where, I ask myself what I expect to need them to do?

I've recently been focusing more on axes. All Gransfors Bruks. Most recently the Splitting Maul and a splitting wedge. Of course, those won't be in the backpack.
