In the woods hunting and something is impaled and needs taken out.
Cutting something open that’s not in the kitchen or the house.
Cutting fishing line.
Cutting up that roadkill rabbit I found while in the way to make some sets.
It doubles as a punch, screwdriver, and machete at times.
Spend lots of time in the woods, I can't remember the last time I came across something "impaled and needed taking out". Did get a fishing lure in my cheek years ago while fishing alone, couldn't see it obviously so I left it there till I got back to civilization and had it removed then without a knife. Pocket Knife would of been of no use at the time.
I usually wait till I get in the house or workshop to cut something open, no need to open it right here right now.
I carry tools while fishing for cutting line and if I'm using fishing line around the house for other uses I have utility knives stored where the fishing line is stored.
Carry a container with tools used for trapping, in there is a knife. Again I don't need to cut up the rabbit right on the road where I find it, I'd toss it in the vehicle and cut it up later when needed.
All sorts of tools can be used for uses other than designed, again, if I need a punch, screwdriver or machete (don't know when the last time I needed a machete was tho) I have those tools and others in a couple of places that I take things when I need to do work on them.
Pocket knifes are useful when your in a remote place, even then if your going there to do a task take the tools with you that you most likely will need. If a knife is going to be needed take a decent knife for the purpose like filleting a fish rather than a pocket knife.But I don't need to carry a pocket knife if I'm working in the workshop or hanging around the house, or driving around in the car. all places have all sorts of other tools at hand.
