In 1845, James King & Co advertised as a manufacturer of table and spear point knives at 115 Scotland Street.  The partners were Thomas Wigfall and James King.  The latter may have been James King, who in 1841 was a journeyman blade maker, living with his wife Hannah and son in Edward Street.  He was listed in the directory (1852) as a table knife manufacturer and victualler at the Social Tavern, Hollis Croft.  He lived in Bailey Street.  James was still forging table blades in 1871, but his later life is unknown.  Hannah King died in Hammond Terrace, Water Lane, on 31 December 1876 (aged 64).  Other James Kings were active in the cutlery trades at this time, which makes identification confusing.  These included James King (c.1818-1866), table blade forger, Weston Street (died 5 January 1866, aged 47, and buried in Burngreave).  Certainly, James King & Co was short-lived: it had been dissolved by the end of 1845.
