Discussing the merits of a big knife with a backpacker is like discussing the merits of a steak dinner with a vegetarian.
Out on your own, on foot, without vehicular or 4 legged transportation "light is right, and lighter is righter." "Ounces= Pounds and Pounds= pain" But, if hiking is secondary to camping, and you aren't going far- by your own definition of far- carry what you want. That said, regardless of how far you are going, carry what you want. But, remember that anything you carry in, you are obligated to carry out.
We are on a knife forum, talking about knives. There is very little NEED that every enters the discussions. This is a site devoted to luxury items filled with discussions about their use. Most of us invent uses for our cutlery because modern life is pre packaged and perforated for convenience. Do you need a big chopper for an overnight camping trip? No. Do you need a big axe? No. As a matter of fact, most public areas prohibit the chopping and/or felling of trees, and what you can gather from dead fall is likely small enough, or can be made small enough to burn without a chopping tool of any kind. But, we bring them along anyway.
For a big chopping knife, I recommend the Scrapyard Dogfather. It is a great knife and the S77 steel is tough and takes a keen edge. For a "sturdy camp knife" I recommend the Busse Sar5- if you can find one. It is big enough for any task that I can readily imagine for typical camp duty, but small enough to carry all day without being a burden. If you are a through-hiker, and camping is secondary to the thrill of carrying everything on your back and walking as far as possible with as little as possible, a SAK camper has a saw and will do anything you need a knife or a saw to do.
