This cutlery firm began trading after 1945. The address was Beehive Works at 165 Fitzwilliam Street. The owner listed in Kelly’s Sheffield Directory (1951) was Cyril Parkin (1903-1967).  He was the son of Herbert Parkin (1877-1928), who had been a second generation partner in W. H. Parkin & Sons – a bone and celluloid handle manufacturer, also in Fitzwilliam Street. Cyril seems to have joined the family firm initially, but by 1939 was working as a departmental manager at a cutlery works (Register of England & Wales, 1939). Other partners in Parkin Bros were not listed, but may have included Cyril’s brother, Frederick (1901-1952).

Parkin Bros advertised as makers of ‘IBEX’ brand and ‘PARKIN EDGE’ kitchen knives (International Cutler, December 1952).  These knives had cups and grooves along the cutting edge to facilitate (it was claimed) the cutting of bread, poultry, and game. The design had echoes of ‘Granton Edge’ knives made by William Grant. Cyril Parkin, of Bishop’s Court, Sheffield, died on 6 December 1967. He left £4,094. Parkin Bros had traded into the 1960s, but was not listed in 1968.
