"Jesus Christ, Himself, could send a bar of steel down from Heaven.
It will only be as good as the heat treatment it gets on Earth."
In other words, there is a long list of steels that will perform the tasks you have in mind, but only so long as the maker KNOWS that steel and how best to heat treat it.
It's not so much a matter of what the best steel is, but who knows how to best create the knife using THAT steel by doing what is necessary for THAT steel.
A mediocre, border line, "nothing special" steel, properly heat treated, will beat the designer, high-tech, expensive alloy steel, improperly done, hands down every time.
