I think the explanation I gave David for the functional requirements was something along the lines of 'a kitchen knife that could be used to hunt pigs'. So it would need to be pointy enough to dispatch a boar (which requires punching through the 'gristle armor' they build up), but tough enough to survive hitting ribs and scraping bone. And then sharp enough to butcher the hog,and then cut it up in the kitchen along with the veggies. And decent enough edge-holding to cut boar hide (their hair is notoriously abusive on knife edges).
I don't plan on doing that often. But as a litmus test, if it can do all of the above, it can do anything else I'm likely to use it for without worry. I can happily use it around fresh and salt water because its close to rust-proof.
