For me, at this stage in my life, camping is now about doing the absolute bare minimum -- "roughing it" not to "endure" but to avoid as many of life's daily tedious chores as possible. So less is more in that regard (i.e. just a knife). At home I use an axe. I am getting a chopper out of pure desire but I am telling my wife I really need it for the brush pile and fire starting. I also have kids who I will let baton smaller pieces with a knife (under supervision of course) but they are in no way ready for an axe or hatchet.
This is a cool video (imho) if you haven't already seen it:
