Robert F Mosley was a Sheffield based cutlery maker who was the first company to manufacture cutlery in what was to become known as ‘stainless steel.
Mosley, based at Portland Works, had a key role in the history of the development of stainless steel. In 1914 Harry Brearley turned to the company to help make knives from his new rustless steel which they did. Mosley’s therefore became the first cutlery company to recognise the value of Stainless steel cutlery and to produce and market it under the RUSNORSTAIN brand.
