1798 Company Established.
c 1925 Darwin and Milner purchased the Sheffield Simplex Motor Works at Tinsley, and set about equipping them for the production, on a mass scale, of safety razor blades. The firm was already engaged in a variety of branches of the steel trade, but razor blade was a new departure and it has now been developed to a very large and promising extent. The blades were made of a patented cobalt steel. The present output was about a million a week, and employment was found for about 1400 people, whom of nearly a thousand were girls, who all work in one great shop that covered an acre of ground.
