Jack Bennett (1893-1972) had been born in Sheffield, the son of John William Bennett (a garden shear forger) and his wife, Ann.  Jack was working in a cutlery warehouse by 1911.  His partner was Thomas Emmanuel Heron (1893-1983), who had been born at Stirling, Scotland.   He was  the son of a Scottish schoolmaster, John William Heron, and his wife, Mary.   Thomas was awarded the Military Cross in the First World War.  By 1921, Bennett & Heron was established as a cutlery manufacturer in Holly Lane/Street.  Later the firm moved to Mary Street, but in 1927 the partnership was dissolved.  Heron became a Christian Scientist practitioner and appeared twice at inquests in Sheffield, after he had attended dying patients (one of them a child) and had treated them by prayer and ‘absent’ treatment.  Coroners evidently disapproved of his involvement (Yorkshire Post, 5 November 1929; Taunton Courier, 8 February 1933).   He later moved to Montreal and died at Toronto.

Jack Bennett, who lived in Spencer Road, Heeley, continued to trade as Bennett & Heron.  Good quality pocket-knives were made by Bennett & Heron, but the firm also produced table cutlery, carving sets, and cutlery canteens.  By catering for the mass market, the company survived the 1930s.   It was listed at Dignity Silver Works in Mary Street and Broad Lane.  In 1956, Bennett adopted limited liability.  He died in Sheffield on 21 September 1972, aged 79, leaving £16,636.  A. N. Wallace became director at Broad Lane, but the firm was no longer listed by the end of the 1980s.   No trade mark has been traced.
