What are Preserve Blades made from?
Preserve razorblades are made from titanium-coated stainless steel, but the clip wires (on the ends of the cartridge) are manufactured using rolled aluminum. The aluminum is then coated with plastic so it will not come into contact with skin. Nickel is a specified component for stainless steel razor blades. It may be present in trace amounts, but the amount is usually too small to detect with standard testing equipment.
