White steel (also known as “Shirogami”) is used to for cutlery products that can be sharpened to an excellent edge with good quality natural stones. It is a carbon steel with only very small amounts of the impurities.
It has a very narrow range of temperatures for hardening (Yakiire and quenching), and thus requires the blacksmith to be very skilled.
The only downside of White-2 steel is that it’s not rust resistant as it contains high amount of carbon so that it requires users a good maintenance practice.
