Blade steel
Stainless steelThe manufacturer does not say which steel this is. "Stainless" covers everything from soft 420J to premium powder steels, so on its own it tells you almost nothing.Treat an unnamed steel as a budget stainless until the maker says otherwise. A maker who uses a good steel usually names it. Editorial guidance, not a measured specification.
