White’s General Directory … of Sheffield (1860) has two spring-knife manufacturers named Needham Bros.  One Needham Bros was in Milton Street; the other was at Cavendish Works, Broomhall Street.   No family connection apparently existed.  The partners at Cavendish Works were Henry William Needham (c.1821-1877?) and Charles Needham (c.  1825-?).   They were the sons of William Needham, who had been born in Derbyshire in about 1790, and his wife Harriet.  William was a spring knife manufacturer.   According to The Sheffield Independent, 31 May 1845, Needhams in Trafalgar Street produced ‘an enormous pocket knife, with scimitar blade 19½ inches long, a haft of angelo-wood 20½ inches long, and mounted in German silver.   Its entire length is 3 feet 3½ inches.  On the shield is the inscription, “Manufactured by Henry William and Charles Needham, and presented by them to the Spring Knife Cutlers” Bazaar, 1845’.   It is altogether a fine specimen of manufacture, and is expected to sell for at least £1 10s’.  William Needham died in Cavendish Street on 21 November 1860, aged 70, and was buried in the General Cemetery.   His wife, Harriet, died in Franklin Street in 1870, aged 81.   Needham Bros advertised from Cavendish Street in the directory (1862) as a manufacturer of spoon-knives and spring cutlery.   However, by 1871 only Henry William Needham appears to have been active as a spring knife cutler (he lived in Franklin Street).  He may have died in 1877.   Charles Needham’s later career has not been traced.
