I do have toughness data for Vanax and LC200N (listed as Z-Finit). https://i0.wp.com/knifesteelnerds.com/w ... =754&ssl=1

I used the results of the study to improve my ranking of corrosion resistance of knife steels. https://knifesteelnerds.com/2019/10/14/ ... e-testing/
I think as far as conventional knife usage goes, XHP is "stainless enough" for 95% of the knife community and perhaps to less of an extent, the same can be said for ZDP-189 and CruWear (I carried a Dragonfly in ZDP-189 as my EDC for years & rusting/staining was never a problem with regular common sense maintenance).
Those cutoff points are going to be highly dependent on the environment they are exposed to. For example, you may not see any difference between BD1 and VG-10 because in your particular use neither is seeing any corrosion.zuludelta wrote: ↑Mon Oct 14, 2019 9:38 amI do think that numerical rating differences perhaps mean different things across the scale in practical terms, at least from my anecdotal experience. As in, it's harder to discern practical performance differences in the upper end of the scale—like the 0.5 difference between BD1 (8.0) and VG10 (7.5)—than in the lower end of the scale, such as the 0.5 difference between ZDP-189 (4.9) and Maxamet (4.4). I'd be hard-pressed to find any practical corrosion resistance difference between BD1 & VG10 in my day-to-day use but (to me, at least) the same cannot be said for ZDP-189 and Maxamet—Maxamet definitely stains & rusts more easily than ZDP-189 upon exposure to things like saltwater and food acids.
It will come! Hopefully the middle of November. My original plan was to do an article on "Carbide replacement high speed steels" around now but other things took precedence.
