The CPM process you describe sounds similar to so-called PMV-11 steel, which is used in some high-end chisels and woodworking planes. It’s not just marketing, several professionals who are mostly impartial have said its noticeably better than conventional tool steels.
There are some nice wear images off the site below as well.

- nordsieck 6y agoNot to derail the conversation, but I spent some time reading about PM-V11. Is there a data sheet somewhere? It looks to me like a mystery steel, which I'm always pretty skeptical of. Specifically: while it's very hard to make a particular steel perform better, it's very easy to make a particular steel perform more poorly. I'm not claiming that they purposefully engaged in malfeasance, I'm just generally skeptical. I'm particularly skeptical of their claim that it outperforms CPM-M4, which is generally used for bladesports[1] for its ability to take a fine edge and resist mechanical edge deformation. I'm not surprised by the difficulty they had in sharpening it, though. ___ 1. https://www.youtube.com/watch?v=YkemT5ciBnw https://www.youtube.com/watch?v=YkemT5ciBnw
