I agree that a decent hatchet would be better than a khukuri for big chopping jobs and definitely better for the way I like to split kindling wood.
I like to split thinner branches for kindling by laying them flat while holding the end of them in my left hand. I then swing a hatchet in my right hand. Because the blade is only about four inches long, and because it is right at the end of a long handle, this is a relatively safe way to split sticks. The shape and configuration of the khukuri blade makes it too dangerous to use in the same way.
When I go trapping I carry a small knife for skinning and odd jobs, but I also like to have a chopper of some sort. I've carried different hatchets and a small tomahawk that I made. They were certainly useful. I might need to cut a bit of scrubby material to clear a trap run or to make a barrier. I also sometimes need to chop a pole to set a snare on....or I might want to remove smaller side branches from a main tree branch that I want to set a snare on. The hatchet can also be used to drive pegs and nails, and it can be used as a club to despatch trapped animals.
I recently bought a couple of Himalayan Imports Ang Khola khukuris to try on the trap line.....a heavy 15-incher (overall length) and a 12-incher. I've also got a Tora 'British Service Issue' which is a lighter blade, but still very effective.
I've taken all of these khuks with me while setting and checking traps, and frankly - for the tasks I've mentioned - I prefer any of these khukuris as versatile trapline tools compared to my hatchets and tomahawk. They are relatively easy to carry, they seem to be much better for chopping standing saplings and scrub....plus they would be much better as a 'weapon' because they can be used for thrusting as well as chopping. I haven't used a khukuri for 'sticking' yet....but occasionally I do encounter larger animals when I'm out hunting and sometimes it is more appropriate to finish them with a knife rather than firing a shot (I may not even have a rifle at times).
A khukuri seems to be able to make a decent cut even if you cant build up much of a 'swing'. This makes it good for trimming branches on a live tree where other branches get in the way....or when working in thick scrub.
If I needed to cut thicker saplings or drive pegs frequently, I'd pick my 15" Ang Khola. However it is fairly darn heavy, so I find that I mostly pick up the 12 inch model, and this smaller khuk has amazed me with what it can do. A short time back I used the back of it to drive some heavy nails that were protruding from some wharf decking. It is no trouble to carry. If I had a lot of lighter scrub to cope with at my sets, and if there was a chance that I'd have a bigger animal to despatch, I'd grab my British Service issue. Although the base of the handle is nearly at 45 degrees from the end of the blade, the blade shape lends itself well to the allotted tasks....plus it is a relatively light knife for its length. All the khuks are good, but the simple 12" Ang Khola would probably be my pick for most trapping work because it is so light and convenient (plus it was relatively inexpensive). I should note that so far I've had to do a lot of walking around my trap lines, so I have to consider the weight and utility of each item of my gear.
However, there is nothing wrong with the hatchets I've used...and I don't even own any of those very attractive and efficient-looking hatchets I've seen pictured on this forum. Mine are mainly old heads that I've scrounged, re-handled, and sharpened. And like I said...for dedicated log chopping and firewood splitting, an axe or hatchet is probably going to be better for the task than a khukuri.
Unfortunately it seems that we'll never have just one blade that does everything well. But it is great to have a choice.
Heres the H.I. 12" (overall length) Ang Khola khukuri:
