I think that's a good point.
With care any knife, or sharp edge ....after all metal working's fairly recent in human history, stone working long predates even Homo sapiens neanderthalensis.....can be used to do anything you need it to do, but, having the 'right' tool to do the job makes the whole thing much easier, simpler and the work just goes well.
That said, few of us carry a tool kit when we're out and about so it's a kind of horses for courses for most of us, and a bit of a compromise usually.
I like little knives, and I carry small pruners
On the whole the classic 'bushcrafter' knife, is pretty bombproof though. From Ray's promoted designs to the Spyderco, and I don't mind the name/Maker of the one that had a butt plate (great for nuts or loosening bark, etc., ) but I liked that one too
they're all sound.
I don't live or wander around locally anywhere where a big knife won't cause comment or raise hassle; the little ones are tidily secure in a pocket or pack.
