Been all over the place on 4 continents. Lost, wore out or broke more knives than most have seen. The constants, for nearly 5 decades, have been basic SAK; and Brusletto tri-lam carbon steel self-hafted hunters when I had to have a fixed blade. Finally went with the scissors over the saw about 10 years ago after EMT classes. Always favored a shorter blade for belt carry. No bowies, no daggers, no fancy stainless stuff...
Big knife..? Khukuri since '69... Bigger...? Engnath wakasizhi I put together in '97 as I recall. Biggest... an old lochibar in the corner for those 'special' guests...
Otherwise, whatever's handy when I need one. If it's sharp it will generally get the job done. Brusletto and some Japanese carbon laminated blades generally hold the best edge for the least money, I've found.
But I like steel, so whatever gets you there is fine. Got so many stashed here and there, one occasionally surprises me when I happen upon it, and wonder why I got it. Just an old man's opinion.
Be well...
