Wilderness, or out camping with items that can break?
I'm specifically thinking about a tool for when I'm actually out hiking or backpacking.
If I'm car camping, or just out in a more remote setting with my vehicle, I'd have access to some basic full-sized tools in my vehicle so what I carry wouldn't be the be all & end all.
Better to have them and not need them ...
Yes and no. I have a limited amount of room & weight carrying capacity when I'm out & about so I want to choose my tools wisely.
