Stainless Steel Blades All steel blades are made of martensitic stainless steel. The basis for optimum function and durability of a blade, is the use of the correct steel alloy. The steel should deliver the perfect combination of cutting edge retention and corrosion protection. It should also be flexible, so it does not break during use.
