William Twigg was listed as a table knife manufacturer in Westbar in 1839.  By the 1850s, Twigg was also a cutlery/hardware dealer in Westbar, though by the end of that decade his address was Bridge Street (a continuation of the same road).  By 1863, William Twigg & Sons was listed at Bridge Street, from where it claimed £140 damages after the Sheffield Flood.  It advertised in the 1868 directory as a manufacturer of table cutlery, bread, butchers, cooks’ knives and steels. 

In 1871, the enterprise employed ten men and three boys.  William Twigg, manufacturer of Bridge Street, died on 4 December 1879, aged 71.  He was buried in the General Cemetery.  The company was located at Bridge Street through the 1880s and 1890s, with William Twigg (one of William Sen.’s sons) as a partner in 1898.  After 1903, the enterprise apparently became defunct.  No trade mark has been traced.
