The strike against D2 for hign end kitchen knife use may be that even when done the Dozier way, it is not going to support that super fine edge like 52100, AEB-L/13C26, W2, the Hitachi steels, 115W8, etc., RWL 34, CPM 154 (to a lesser extent) or even weird harder to work with stuff like CPM 3V or CPM M4. I noticed that after using CPM 154 and later, CTS-XHP, Joel from Cut Brooklyn has now switched over to AEB-L for his stainless knives and 52100 and 1095 for the carbon models. Now why he is charging 75% more for 52100 than 1095 and even why he is using 1095 for his lower priced blades I can't tell you, but there it is. Aldo's 52100 only costs about 5-6% more than his 1095.
I'm gonna be blunt. Joels's new, but not that new.For the price he charges for stock removal any of us could get a handforged piece of 52100 from an ABS mastersmith. It's just spring steel, but the two couldn't be further from each other on the spectrum, they only share the price.
