I'm a skeptic on the subject of choppers. I don't get them. At all.
Can all you chopper fans out there educate me on the sorts of cutting tasks that you like a chopper (knife) for better than an axe/hatchet or a machete?
I doubt that I can educate you other than tell you what I think and do. For chopping tasks (trees and stiff material over 1" diameter) I would take an axe every time if it didn't mean me lugging an axe for miles. It is not always about carrying the most efficient tool for a job or a likely series of tasks in a given scenario such as camping.
If I am not going to be likely doing much "chopping", then I would lean toward a short machete (a stiff one which is essentially a large chopper knife) over an axe or hatchet.
Hatchets are not something I see much need for unless you need the utility of cutting something and being able to pound something (nails, stakes, and so forth). That is about the only time I would choose a hatchet over a large knife... usually short machete for me.
Would I carry a short machete every time I believe I will need to chop? Probably not. But I might take one along if I know I will likely be clearing a trail, even some flexible stuff of short duration. If I know I will be doing a lot of thin or flexible material cutting, I would take a regular machete.
I would take a large knife if I see little need to chop because it does introduce some flexibility and often is smaller and lighter than an axe. But if I know I have to cut larger trees down, I'll carry that axe and a smaller fixed blade for other tasks. The thing is I seldom see a need for a large knife especially if I have a little folding saw with me. The only selling point for a large knife to me is that it can be used for smaller cutting tasks. But I usually have a folder for that.....
So, it is all about perceived need and personal preference. My preferences are short machete (larger than most "large knives") for chopping over a large knife (an example is a BK-9) or hatchet. But it comes back to what would I really need that the flat top of a hatchet for to make me want to choose it over a short machete.
So I am certainly biased in my choices. I seldom cut big stuff in the woods that requires an axe if I am carrying it (lugging it) by foot. Most needs would push me toward a chain saw if I need to cut a lot of bigger stuff and especially if I can drive there and park nearby. I would walk back for the chain saw when the need develops. I have cut a lot of larger stuff camping with a saw of some sort. Chain saws weren't an option for the most part due to noise and bringing too much attention to your cutting activity.
I have to think about taking a large knife with me in the woods. I normally don't. I'll have a medium sized knife (4-6" blade), a handly folder, and a folding saw. So, I am pretty much in your camp from the way I interpret your question.
