John Newbould was born in Sheffield on 27 July 1812, the son of William, a cutler, and his wife, Frances.  He was one of the Newbould Bros.  According to an advertisement, John Newbould & Co was established in 1840.  It operated from Eyre Street after 1856 and advertised in Birmingham and Sheffield directories as ‘late Newbould Bros’, Eyre Street, selling table cutlery and Bowie, dagger, and spear knives.  In 1867, John Newbould, the table knife manufacturer, was bankrupt.  However, his fortunes apparently recovered.  In 1868, the address of John Newbould & Co was Surrey Works, Eyre Lane, the former address of Standfield, Newbould & Baildon.  The directory for that year carried an early advertisement for the firm. 

In 1871, it was listed in Eyre Street, as a merchant and manufacturer of table cutlery and spring knives.  By the end of that decade, the firm employed 40 men and 10 women.  In 1886, John Wigfull, who was John Newbould’s partner at that time, withdrew from the firm.  John Newbould, Brincliffe Edge Road, died on 19 December 1888, aged 76.  He left £2,542.  The stock, tools, and machinery at Surrey Works were auctioned in 1892 (Sheffield Independent, 26 March 1892).  John Newbould & Co was listed at Continental Works, Milton Street, in 1893.  Between 1895 and about 1925, a firm of that name was listed at 90 Mary Street.  It disappeared after that date.
