There are many companies that bring us knife steel, from steel manufacturers to a whole array of suppliers to individual custom knife makers. So I have written a bit about how the supply chain works and some information on individual steel suppliers.
There are quite a few companies that produce steel used for knives. These are the companies that melt the steel, add the appropriate elements, and cast it into an ingot. Many of these same companies also hot roll and anneal the steel and perhaps cold roll it. Some of the better known knife steel manufacturers include Crucible (S30V, S35VN, CPM-3V, CruWear, CPM-M4, 154CM), Carpenter (CTS-XHP, CTS-BD1N, Maxamet), Hitachi (White #1, Blue Super, ATS-34, ZDP-189), Uddeholm (AEB-L, Elmax, Vanax, Vanadis 4 Extra), Bohler (M390, N690, K390), and Sandvik (12C27, 14C28N). There are also many other steel companies that sell “standard” or lesser known steel grades like Aichi (AUS-8, AUS-10), Ahonest Changjiang (8Cr13MoV, 9Cr18MoV, 7Cr17), or Latrobe (BG42, 440C, D2).
This article is a bit different than most Knife Steel Nerds posts, but it is a great reference of the major players in the steel arena.View Linked Article
