I respectfully disagree. Listening to "empirical information" is not the same as testing things for yourself. Nor did I suggest the OP should buy a bucket of misc knives from Frost cutlery. If the OP listens to the steel junkies he'll come away with "empirical information" that 12C27 is a low end steel and not to bother with anything in 12C27. But he could get two Moras (or two Opinels) for $20, and see if stainless suits his needs better than carbon. If he lives in a humid climate he might like Sandvik but decide the Mora's scandi grind isn't the best for his needs. Plus he now has two hard working (albiet low priced) knives for camp, kitchen or BOB.
Also, much depends on his level of skill in sharpening, how much time he's willing to devote to reprofile an edge, or even if he has a diamond stone set-up. S30V is one of the darlings around here, but I've seen it chip and the nicks are a pain to get out. Nor would I want to attemp to put a convex edge on it without a belt sander. ZDP-189 is still a gotta-have-it steel but somebody here broke it on sheet rock. If the OP needs a tougher knife then this darling may not be for him, no matter how much "empirical
information" there is.
With brick and mortar shop going the way of the dinosaur I rarely get to handle knives before buying. Unless the OP is lucky, and lives next to SMKW, he's probably going to have to buy online, sight unseen, like most of us. I don't know about the OP but I do consider Sebenzas to be expensive. They're not in my budget, no matter how nice they are. And not everything less than a Sebenza is half assed. He could get a Canal Street and a GEC for less than half the cost of a custom. Niether are what I would call half-assed knives.
Sure, you can narrow your search by listening to other people's experiences but there is no substitute for your own experience. And that was my advice to the OP.
