William Sayles (c.1790-1835) was first listed in a directory in 1821 as a grinder in Solly Street.  He may have been related to William Sayles, of Sayles, Hancock & Co.   In 1822, William Sayles in Solly Street was listed as a pen, pocket, and table knife manufacturer.   By 1825, he was operating at Norfolk Street as a table knife manufacturer and dealer in cutlery.  He was absent from the Sheffield directory in 1828, but The Sheffield Independent, 14 October 1826 perhaps offers a reason.  An advertisement for William Sayles, Wheeldon Street, offered for sale beer machines (and emphasised that Sayles also sold brass front cocks and tapping cocks for beer machines).  In 1833, Sayles appeared again in a directory as a cutlery manufacturer at Colliers’ Row, Wheeldon Street.  He died on 15 May 1835, aged 45, ‘deeply respected by his family, and much respected by a numerous circle of friends’ (Sheffield Independent, 23 May 1835).  He was buried at St George’s, Portobello.
