This firm was launched in about 1893 as a merchant and cutlery manufacturer at Gibraltar Works, Gibraltar Street.   The partners were from Ecclesfield: Edwin Arthur Green (1863-1946) and Walter Ernest Green (1866-1942).  They were the sons of William Green, an iron founder and stove grate manufacturer (from Saxton), and his wife, Elizabeth.  In 1871, William Green employed forty workers at foundries in Corporation Street and Ecclesfield.  He died at Ecclesfield Common on 6 January 1872, aged 48, and was buried in Ecclesfield, leaving under £100.  

In 1896, Green & Green became  a private limited company (capital £10,000) and registered a silver mark from Mitre Works, Gibraltar Street.  The firm used the ‘GRINDER’ mark; and owned the names ‘Thomas B. Hague’ and ‘George Wilkin’.  By 1899, the address was 97 Edward Street, when a fire gutted the factory.  Apparently, eighty workers were employed at Mitre Works, which was a three-storied block around a courtyard (Sheffield Independent, 5 August 1899).   By 1911, Edwin had moved to Bath and was working as an ironmonger.  He had retired by 1939.  He died on 21 September 1946, leaving £1,016.

Green & Green had ceased operating.  However, Walter Green Ltd, table and pocket knife manufacturer, had appeared in Pond Street.  In 1913, the address was 105 Edward Street.  In 1918, the premises (which were shared with Egginton Bros) were extensively damaged by a fire.  The damage, estimated at £1,500 to £2,000, was covered by insurance (Sheffield Daily Telegraph, 15 March 1918).  The firm employed about nine workers.  Walter E. Green died on 17 June 1942, leaving £1,080.   Walter Green Ltd apparently ceased trading at that time, when it was in Orange Street.  The ‘GRINDER’ mark was later owned by Herbert Robinson.
