I have CS S35VN, too, my Espada XLI have PM2 in Cruwear, M4 and Endura in ZDP189. I don’t have Spyderco heat treated S45VN but I have CS S35VN.
First, I would not dismiss VG10. It’s a great steel, easy to sharpen, could be fairly hard depending on the HT and it takes excellent edge. Won’t rust as M4 or stain as Cruwear or ZDP189.
About the steels, I would put the ZDP189 to be the hardest one, followed by probably Cruwear and S45VN and VG10 being the “softest” sort of speak.
Toughness would go probably in opposite way as VG10 being the toughest or maybe share same place with S45VN for what I can observe from my S35VN use of the Cold Steel blade, Cruwear and last - the ZDP189.
‘With this said, I don’t find my ZDP Endura to be brittle… Factory edge is very sharp and I still didn’t need to put new edge on it. I’m not too much into charts and such technicalities but it does have such a thin stock behind the edge that I think if I give it 15-16 degrees angle per side, it will outlast the factory edge…
‘However im in the same page as you, but for different reasons, and will probably give her sharper angle, like 14 per side…
K390 will probably top all of those steels in terms of toughness and hardness, the two things I care about.
Ill get soon Police 4 in K390 and then I’ll have some impression how it compares to the rest of the steels Mentioned.

Oh, I have not dismissed VG-10, I have it in a Matriarch 2 and intend to get a Centofante slicer with a saber grind so the tip is stronger than most Spyderco knives! It seems like quite a good steel, and the stainlessness. I was under the impression that Cruwear was a great all-rounder, that actually is stainless enough for a non-stainless and easy to sharpen while taking the qualities of harder steels like S110V (not THAT much edge retention). But it is hard for me to see becaue there are not a ton of charts, just peicing together info.
I would LOVE a Police in K390, the ones that say SOLD OUT on BHQ are those from a past release, or are there ones coming? Someone said that my ZDP would make it redundant to get a K390, but I am unsure of that, see brittleness.
Oh, I didn't mean modify it, I meant just adjust it's purpose once I get a second one. It already has the hawkbill (well, reverse S) shape conducive to mushroom slicing and those insane serrations would make it a great mushroom slicer. Got my girl an Opinel 8 mushroom knife, and I want to, for a laugh, have the baddest mushroom harvesting knife ever. Going to get a black DLC one so I might use that, just for the added "black knife" factor, just the most intense mushroom knife everCurious, what do you plan on doing to a Matriarch to make it a mushroom-type knife, besides harvesting mushrooms with it (kinda assume blade grind modifications) ?

Though, once I learn the stones better, I wonder if there are any modifications to be made!
