In 1960, Gillette introduced the Super Blue blade, the company's first coated blade, and the first significantly improved razor blade since the Blue Blade of the 1930s. The new blade was coated with silicone and in Gillette's laboratory testing produced much more comfortable and close shaves by reducing the blade's adhesion to whiskers. Super Blue was a success and sold more than the Blue Blade and Thin Blade combined. By the end of 1961, Gillette's double edge blade market share had risen to 90 percent and the company held a total razor blade market share of 70 percent.
