At the Great Exhibition (1851), Joseph Rodgers & Sons displayed its giant ‘Norfolk Knife’.   Rodgers’ company history, Under Five Sovereigns (1911) stated that it was made by ‘a workman named William Bamforth, two years being necessary for its manufacture’.  He was likely the ‘sportsman knife maker’ of that name enumerated in the Census (1851).  He had been born in about 1803 in Nether Hallam and was living in Meadow Street.  He later moved to Orchard Road, Walkley, where he died on 12 December 1870, aged 67.   His obituary stated that he had worked for Joseph Rodgers & Sons for over 33 years.  He was buried at Wardsend cemetery.  He left effects under £100.   A letter in The Sheffield Independent, 20 October 1892, placed him among ‘some of the most skilful cutlers in the world’
