Off Topic Stopped caring about edge-retention

[c7m2p3]

I prefer to have a hair popping edge and resharpen often rather than a long working edge. I wish S30V and the other S??V steels weren't so prevalent, they make sense for the majority of the knife buying public that appreciates a working edge for a longer period and may not be as caring or even able to get and maintain a scalpel like edge for use.

I do however like good D2 with a toothy edge, cuts like a demon in my experience, but generally prefer finer grained steels and am very happy with 14C28N, N690, 154CM, 440C, 12C27, 1095, and VG-10.
I want to try M390 as its a steel I haven't used before.

M390 Will take a hair popping edge with diamonds fairly readily in my experience. I appreciate a hair popping edge as well but I also have to recognize that it is nice to have right after I put it on but cutting virtually anything is going to turn it into a working edge even with very hard premium steel.
