Mora use 12C27, which isn't a bad stainless, a lot of very experienced makers and users like it but it is a cheap steel, and only gives its best with cryo treatment (source-Alan Wood & Mike Lamprey). As treated by Mora the stated hardness range is 56-58HRC. At 58 it will be reasonable, at 56, poor. By comparison, the carbon steel version is hardened to 58-60HRC. It is quite possible that your comparison blades were quite a distance apart in hardness.
It is a shame to tar all stainless steel with the same brush based upon a sample of one. Don't discount the idea of making yourself something in a high end stainless one day. That is what I did. I have used essentially the same knife in O-1, 12C27 (cryo) and RWL34 and for general use, the RWL34 has been the winner.
This makes interesting reading.
In its most basic form, steel is just iron and carbon, but people have been studying, experimenting with, and perfecting steel with other elements for specific applications for millennia. The study of steel is now so complex and nuanced that one can acquire a graduate degree in the subject and...
