Thanks for posting the data from Sandvik. It does look like better steel than I thought.
As a side note, I don’t think I have ever had a pocket knife or sheath knife rust or corrode. Even my cheap edc has never had a spot of rust on it, and well, living on the beach and sweating in the garden and yard in the summer time you do get both salty and sweaty. I don’t necessarily remembering giving the knives in my pocket or yard pouch any extra care other than wiping them down and giving a little sharpening love, even when I couldn’t sharpen worth beans…
