Introduced in the United States in the late 1950s, Wilkinson Sword's original stainless steel double edge blade became an immediate and lasting success because of its fine edge. Today's Classic Double Edge blade retains the original precision-honed Wilkinson Sword edge, but has been improved by Wilkinson's famous triple coating process of chromium to resist corrosion, ceramic for added durability, and PTFE for less irritation. The result is a blade that maintains its edge even longer than stainless steel for incredibly smooth, close, and comfortable double edge shaves. Fit all standard double edge razors.
