What is the difference between blue super steel and Hitachi white steel on FS1s?

The idea with the blue super and 1035 spring steel is that it is practically indestructible; also, the strength per weight ratio is the strongest we offer.

The white stainless gives you a keener edge and sharpens easier; the stainless steel makes it easy to maintain, but typically, we leave them heavier to compensate for the fact that the laminate is not as tough as the blue super 1035 combination.
