Wow that's about perfect for m390 seems like maybe oil quenched from 2050f then tempered at 300f is my guess. I'd love to see a relative cut test with these. Really wishing I liked brown about now
Yes, this really is unicorn territory, for M390. As far as production knives go. It needs to be in this range, or higher. To get the premium cutting performance we are looking to get, and were sold, by knife manufactures.
Personally, I can hardly wait for this steel to completely go away. It must be a Herculean effort, to get it this well done. It's only the third knife, ever, that we have found. That attained this level of hardness. Out of the 45 or so M390 knives, that have been tested so far. From about a dozen different knife manufacturers. And 90%+ of those knives, have been below 60 HRC.
The only other two knives found, to be done this well. Were also Spyderco knives. They are the BBS PM 2 M390, and the DLT PM 2 M390.
