Most products use either chrome plating or stainless steel for protection against rust, these Shark Super Chrome Double Edge Razor Blades use both. First, each of these razor blades have been made using stainless steel, meaning that moisture cannot penetrate the chromium to get at the steel. Second, these razor blades are then chrome-plated so that more chromium sits atop the stainless steel, though the chromium’s brilliant shine can also be a selling point. Of course, these razor blades also bear superb cutting capabilities, having been honed to even edges for close and comfortable shaving.
