Well, truly stainless steels sacrifices a lot of toughness and edge retention. If you have that seawater use-case I guess H1 or equivalent with serrations must be pretty nice to have.
I was wondering if anyone would mention Veff Serrations. I’ve been meaning to try them but wasn’t fully satisfied with any of the offerings for the price. I saw a video where they showcased those serrations and it was pretty impressive.
