"I really love AR-RPM9. It's one of my favorite steels. The first batches Artisan did weren't the greatest, but they have it dialed in now. Easy to sharpen, great stainless qualities, decent toughness, and edge retention that can compete or beat any other budget steel. Edge retention is higher than Civivi 9Cr, toughness is a bit less, stainlessness is about equal. From my experience." (Gideonsstuff)
That would be awesome but I'm still skeptical. One thing that pushes my skepticism here is that AR-RPM9 should have more toughness than 9Cr18Mov, not less. In theory, a major point in making a PM version of 9Cr18Mov is to decrease grain size and increase toughness. In practice, most of the positive reports I've seen have mentioned improved toughness (and improved corrosion resistance).
Comparisons with 14C28N, such as in the other quote, may well be trading on the increased toughness and corrosion resistance I've seen in those anecdotal reports.
