Trying to come up with a list of knife (scissor, razor) steels. Not steels designed for other jobs but then used in knives (so, not die, high speed, bandsaw, hobbing, structural, etc)

Took a look at Zvi's site and am starting with this. Trying not to repeat the alloy content under different names. Like, the composition of 12C27 matches many other cutlery steels, but I'm only listing 12C27.

14C28N, 7C27Mo2, 12C27, 12C27M, 13C26, 19C27
S30V, S35VN, S45VN, Cru Forge V
0170-6
125SC, SC145
BDZ-1, 19C5Va
1K6, 7, 8, 9, 11, Cowry
70x16MFS
Acuto
Gin 1, 3, 5
Nitrobe 77
Aogami, Shirogami, Kigami series, ATS-314
basically everything Takefu?

Manufacturer specific
LV-04 - Lone Wolf
Infi - Busse
ATS-55, SPY27 - Spyderco
N690Bo - Boker (not even sure if there's a real difference)
TKC - Kikuchi
MVS-8 - Masahiro
XT-80 Katz

Not sure if RWL34 fits. The composition was created for jet turbines, but it is a PM version and named for Bob Loveless.

Ultimately just looking for a trend in properties and performance. My theory is that the majority of cutlery used by the majority of people is very well constrained in the properties needed and desired, and the mills and makers are gravitating towards it naturally. Most other steels adapted to cutlery (in wide use) would also fall within the performance parameters of these cutlery-specific steels, despite the difference in original intent and the alloying used to meet that intent.

Please suggest any that are missing or correct for any that should not be included.
 
you're missing 420hc - which buck uses as their standard; it performs really great with the bos heat treatment

the overall trend is easy to follow - we've been giving up toughness to get high edge retention for the last couple decades... only outliers like 3v break this trend ; ) (which is a good thing imho)

How about CPM SPY27? It’s a new steel made exclusively for Spyderco. H1 is another possibility, I don’t know of it being used for anything but knives.
