The custom XM18 is for the most part 20CV. At blade he introduced what looks like a stainless particle D2. I don't know what the average new make is currently.
More accessable, SOG has a fixed blade "team leader" IIRC, in two versions. 20CV
http://sogknives.com/store/TL-01.html, and a cheaper "lite " version with 8a or 440c, I can 't recall. I have one in 20 CV. The design is not a camp knife, a chopper, or a traditional hunter. It's so pointy I believe it would go through a level 3 ballistic vest.
It works, sharpens, and even smells like a tool steel. It's a good steel IMO, but I'd prefer S90V. It does wear harder than S30V
The numbers on wear resistance put out is
440C, being reference standard is %100
154cm is %120
S30V is %145
20Cv is %180.
That's what Latrobe says. Data sheet here:

I do seem to recall custom maker Lightfooftusing it in his line of customs for a while( 458 magnum maybe), but has moved on. ( BG42 last I saw over a year ago I think....but am not sure)
Anza knives are using file steels, most likely W1
W1 appears in some zone tempered knives here on the custom forum from time to time.
Believe it or not I got a Pakistani knife made from File steel ( sawmill cutlery) from Smokey mountain for about 5 dollars. It was a real file, and took a good edge. The first ever in my experience with Pakistani knives. I swear they even smell bad coming out of the boxes from Pakistan. Fit and finish were of course junk. Here it is ( * note : not deal spotting, they have been out of stock for a while.)

My Anza is great. I love it even though it's smaller than the folders I carry.
Best bet are the SOG team leader, and Anza IMO, unless you want a custom made.
Good luck, and if it works out let me know how you like the two steels. Joe
