What do you mean by the question? Laminated steel is simply steel that's been... uh, laminated. Different types of steel with different properties 'sandwiched', typically to create a knife that has a hard edge that stays sharp longer, and tough sides of softer steel so the knife doesn't snap apart at the smallest sign of lateral pressure. The technique was already used by Vikings.
I like the laminated VG-10 Fällkniven uses. The sides scratch easily, and the edge chips easily if you for some reason feel like pounding metals or rock with it, but otherwise the knife takes a beating and stays sharp a good while, and above all cuts well.
