In 1852, Benjamin Hancock (born c.1825) was listed as a spring knife manufacturer in Radford Street.  He lived there with his wife, Elizabeth.  Hancock advertised in the Sheffield directory (1859) from St Philip’s Works, St Philip’s Road.  His works address was later Bramwell Street.  In 1874, he became insolvent, with debts of £1,935 against assets of £1,272.  The business was revived as Hancock & Cooke, St Philip’s Works, Leicester Street.  But this arrangement with John Charles Cooke ended in 1882, when Cooke (a grocer and beer retailer) agreed to pay the partnership debts.  Cooke remained mired in these liabilities (Sheffield Daily Telegraph, 13 January 1885).  Benjamin Hancock’s death has not been traced, but it may have been in 1899.  He may have used a mark ‘B. HANCOCK 44’ later owned by W. A. Colley.
