The Wostenholm trademark was first registered in 1787 and today George Wostenholm & Sons forms part of The Egginton Group in Sheffield. The Group also includes two other world famous historic Sheffield brands - Joseph Rodgers and Ibberson. They produce a wide range of high quality cutlery using traditional and innovative methods, specialising in knives and sharpening steels (steel rods used to sharpen blades). Many of their products supply niche markets, such as the emergency services and catering professions.
George Wostenholm was responsible for much of the development of the Nether Edge area of Sheffield. In the 1830s he purchased a large area of land east of Brincliffe Edge and modelled the estate on the town of Boston, Massachusetts. This included lining all of the roads with trees. Many of the homes in the area are spacious Victorian houses that were owned by local cutlers and business men. Wostenholm himself lived at Kenwood House, now a hotel.
