Depends on the type of knife I guess. If we're talking fixed blades with "entry level" steels I look for 52100, 10xx, AEBL, 14c28n.I'm not so sure. I think on low end knives people perceive it as better than the typical budget steels. With a very good heat treat it seems to punch above its weight.
VG-10 comes to mind. What other steels do you prefer in the low/mid range ?
In folders, certainly, you see carbon steels less frequently.. especially these days. AEBL or NitroV are affordable and I'd personally prefer them to D2.
Now of course with that PM2 you're getting D2 from Crucible and you KNOW the HT is quality.
I guess really these days, knife consumers are spoiled by a glut of high speed, particle metallurgy AND more wide spread knowledge of heat treating cycles and what that means for carbide formation.
D2 is perfectly capable. In 2024 I just think it suffers from not being the hot new shit like it was 20 years ago.
8-12 years ago there were some Chinese manufacturers claiming D2 and it either wasn't, or was HT so poorly it was borderline Pakistani. That probably plays in to my knee jerk reaction when I hear "D2" anymore, even though I know better.
That said- I'm always looking for a PM2 in 52100. I missed out on that one and I can never seem to find one before it's swiped.
