In 1797,  John Ellis & Co, pen and pocket knife maker, was listed at Arundel Street (trade mark ‘ELLIS 607’).   Four years later, a silver mark was registered by John Ellis (presumably of J. Ellis & Co), Peter Spurr, and Peter Cadman at Arundel Street.   That remained the firm’s address in subsequent directories, in which it was listed as a pen and pocket knife manufacturer.    On 9 December 1820, The Sheffield Independent, reported the death ‘yesterday week’ [1 December] of John Ellis, merchant, of John Ellis & Co, Arundel Street.  His age was not stated and his burial has not been traced.  Spurr & Cadman was the ‘successor’ of Ellis & Co, until the former  was dissolved in 1823 by Peter Spurr and Peter Cadman.   Spurr later offered for sale the Ellis workshops, cutlery stock, and tools (Sheffield Independent, 21 August 1824).
