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.
