The Sheffield Independent, 1 March 1851, featured an article on ‘Youthful Ingenuity’.  The youth was an 18-year-old apprentice, William Unwin, who worked and lived with Joseph Foulstone.  Unwin was a spring-knife cutler, who had been spurred by the Great Exhibition in London to make a showpiece sportsman’s knife.  Hafted in stag and in a Wharncliffe pattern, the knife contained three blades, a pair of scissors, two saws, a lancet, a nail file, a cigar holder, a button hook, a horse hook, a corkscrew, a gun screw, picker and tweezers, and a brace borer.   According to the press report, it was regarded by those in the trade as a ‘very superior piece of workmanship, and far beyond what it was thought any youth in the trade could accomplish’.   The jurors at the Great Exhibition agreed: they awarded William Unwin (aged 16, according to the Jurors’ list) a Prize Medal for his sportsman’s knife.   Unwin’s subsequent career and life cannot be tracked with certainty, because more than one William Unwin lived in the town at the time.  It seems likely, however, that this William continued to work as a spring-knife cutler in Aberdeen Street.   He lived with his wife, Sarah, and their children.  By 1881, he was working as a sanitary inspector and continued in that job until his death at Kaye Place, Barber Road, on 28 June 1899 (aged 66).   His wife, Sarah, had died in 1879, aged 45.  Their remains lie in the General Cemetery.
