SLD steel is Hitachi steel co.'s version of SKD-11, which is a wear resistant and relatively easy to maintain steel. This makes it an ideal steel for workhorse knives. With a hardness of 60-62 HRC, SLD steel blades retain their edge for a long time and have the ability to be sharpened to a razor sharp edge. Basically, SLD is used in the factory to cut other steels and, over time, has made its way into high-end Japanese cutlery.
