IMO a blade isn't a necessity for camping. Is it for fires? Are fires a necessity? I cook with a little stove. I like fires for pleasure at night, and for that my 4" mora is largely a convenience item for making fires, for shavings and kindling .... maybe opening food packages too. Without my little knife fire building would be a PITA but it would get done, with some delay. If it's wet or otherwise weather is bad, I probably would be in tent.... again fire a non-issue. When I camp over 3000 ft elevation in Wa state, fires arent a good idea anyhow. If we're talking about hypothetical survival/emergency situations I wouldnt want my warmth/life to be contingent on a fire... there are other ways to keep warm. In my defense I'm just a product of my learning.
Ok, different style of camping, and you carry a 4 inch Mora. From your first post it sounded like you were talking about no blade when camping. I can't get by with out a knife at the house.
For the un experienced lessons in even a small knife can be helpful. Not just how much you can do with a small knife but more important what you can't do with it.
For an extended stay on a primitive sight with a group of people I would expect to process wood for fire. Depending on the size of the group and length of the stay this could be quight a bit of wood. Yes I have processed fire wood with out a knife. I have also found when camping with people who only carry a SAK or what I would think of as a minimal knife they want to use my larger knife/hatchet as much or more than I do. They just don't want to buy or carry it. (not saying you are like that)
I would probably carry both (at least to base camp) but I already own them. If I could only have one I would lean to the HI Kukri for its versatility and durability.
