>>2557485I own both in carbon and stainless.
From left to right: HD stainless, HD carbon, standard stainless, and standard carbon.
For me, HD moras are the obvious choice, mainly due to the slightly more obtuse edge grind. I've had problems with the standard mora rolling its edge during fairly normal "bushcraft" use. The standard mora has a 22-degree edge, whereas the HD mora has a 27-degree edge, making it more robust.
If you live in a wet climate, I'd recommend the HD in stainless steel; if you live in a dry climate, I'd recommend the HD in carbon steel because rust will not be an issue. Plus, the carbon steel version is easier to sharpen.
I live in a wet climate, so my pick is the HD in stainless. Great knoife.
