There are literally thousands of types of steel. Among them, the most common are carbon steels, alloy steels, tool steels, and stainless steels. Each of these types of steel has a designation system that gives them a specific number.fter the two different steels are folded together, the steel is acid etched. The color contrast and patterns on the blade comes from the fact that the two types of steel etch differently.
