Stainless steel was invented in 1913 by Harry Brearley of Sheffield, working for Firth Brown Steels (now called Sheffield Forgemasters). SAE 304 stainless steel is the most common stainless steel today, invented by Dr William Herbert Hatfield FRS in 1924 at Firth-Vickers known as Staybrite 18/8, a chromium-nickel steel. Many Swiss watches were mostly made out of Staybrite.

In 1889, James Neill patented composite steel - steel-backed iron. He registered his composite steel products under the "Eclipse" trademark in 1909. The name was taken from the famous racehorse "Eclipse", who even though he had died over a hundred years earlier was still famous for his dominating success. The phrase ""Eclipse first and the rest nowhere"" was still in such common use that Neill adopted it as a marketing slogan for his products.
