Suppose it depends on the knife/use. I've heard plenty of good, though my only experience is with a newer Hudson bay, which would roll, *bad*, when I chopped wood (like delimbing 1/4" branches from a walking stick destroying my edge...), but I reduced the edge angle with a file (which makes me inclined to think it is low 50's hrc, as the file bit very well) and it seems to be okay now. Not sure if it was the pseudo-scandi grind, soft steel from factory sharpening, or just run soft, but other than that I've had no rust at all which is surprising as it lives in its leather sheath.
I'd feel no hesitation to buy condor again, very good, interesting knives, with great sheaths, at a great price point. Just don't expect perfection (my Hudson bay has a mild twist to it), and you'll be golden, and I imagine smaller knives are only going to be better.
