SG2 (SPG2, Super Gold 2) is a corrosion-resistant powder stainless steel with a fine-grained structure. Developed by the Japanese company Takefu in 1991 specifically for table and kitchen knives. It holds laminated coating well, as well as ceramic and non-stick coating. The manufacturer claims that the hardness of the steel is no more than 62 HRC. Other sources indicate an achievable hardness of 64 - 65 HRC.

CPM S110V is a high-alloy martensitic stainless tool steel manufactured by the crucible metallurgy process (CPM). CPM S110V (cpm-s110v) contains a high volume fraction of both vanadium-rich and niobium-rich primary alloy carbides for good wear resistance compared to other commercially available tool steels. It also provides better corrosion resistance than 440C or CPM S90V.
