If I can get away with using a Golok I will. It is the most versatile tool for what I do and where I'm at in most instances. My camps are usually small and minimal impact, even when they go on for a few days. The woodland here could be hard or soft but either way if I'm not cutting through stuff bigger than my wrist the Golok can handle that easily. That's often the case. I'm not sitting yards away from the fire in some camping chair needing enough heat and light to warm a village.
However, when it comes to winter, or to hardwoods exclusively, the ax is my default setting. Despite some of the nonsense spoken about other sorts of choppers an ax is fundamentally different. It is a simple machine, it is a wedge. Yes you get little axes that try to be knives too, but there's no escaping the raison d'etre of the axe is it is a wedge. And if you had a knife that made for a good wedge it would be pretty darn compromised as a useful knife / machete. Which is why so many have to augment them with an extra step, beating on them, or introducing yet another component, a wedge made from something else. The choice is clear. You either burn up a few more calories carrying an ax, or you conserve them by not taking one and use them up + some later augmenting your alternative and less suitable tool. Further, let's consider the way and ax transmits energy compared to a big knife or machete that has its weight distributed far more evenly along its length. Clearly the ax wins for the same reason nobody of any worth makes hammers that are shaped like oblong rods.
