Durham-Duplex has come a long way from its beginnings as a shaving company in Mystic, New Jersey to become a international manufacturer of Machine knives and Industrial blades operating from 3 factories and across 50 countries.

Durham-Duplex is an international company with distribution across the World with manufacturing centred in 2 factories and a warehouse in Sheffield plus an ASEAN hub in Thailand. The company maintains the ability to manufacture its range of over 14,000 different machine knives and industrial blades.

Durham Razor Company Inc was founded in New York and set up manufacturing in Mystic New Jersey to make the revolutionary Durham-Duplex safety razor system, which is where the unusual name comes from. This innovative product was considered to be a major advancement in shaving especially in comparison to the traditional cut throat razor. The Durham double edge steel razor blade could be re-sharpened on the strop almost indefinitely, but eventually they could be disposed of and replaced without needing a new handle - offering both a considerable saving and a safe way to shave.
