This enterprise sold a wide range of cutlery and edge tools (including table and pocket-knives, saws, files, and steel).   It began as Yeomans, Yates & Standfield, which was listed in Eyre Lane in 1837.  Its merchant partners included John Yeomans (1797-1859); Jared Yates (1786-1842), and William Standfield (1809-1847).   Yates had been baptised at Masbrough Independent Chapel, the son of Samuel (a bookkeeper) and his wife, Mary née Lockwood.  He was apprenticed to Joseph Yates (knife maker) and granted his Freedom in 1840.   Standfield may have been born in Somerset.  By 1837, he was living in Sheffield, but the Census (1841) recorded a visit to Warminster in Wiltshire.

Jared Yates withdrew from the partnership in 1839.  The business continued as Yeomans, Standfield & Newbould.  The new partner was William Newbould (1814-1873).  John Yeomans left in 1844, when the partners became William Standfield, William Newbould, and Henry Johnson.  The latter may have been linked with Christopher Johnson.  He withdrew in 1846, when Standfield, Newbould & Co was already trading.  William Standfield, who may have been on a business trip to the West Country, died ‘almost instantaneously’ at the Duke’s Arms, Marlborough, Wiltshire.  Late in the evening of 4 February 1847, he had ‘walked to the post office, put in his letters, and was a corpse in less than an hour.  Disease of the heart was the immediate cause of death’ (Sheffield Independent, 13 February 1847).  Aged 38, he was a ‘remarkably sober, and … quiet, abstemious man’.   His unconsecrated burial was in the General Cemetery.

By 1849, a fresh recruit was found in Joseph Baildon (1815-1881), a Coventry-born merchant and manufacturer, who lived at Hanover Square.  In 1849, he had married Ann, the daughter of file manufacturer John Martin.  The company name was retained briefly.  History, Gazetteer & Directory of Warwickshire (Sheffield, 1850) carried an advertisement for Standfield, Newbould & Baildon, at Surrey Works, Eyre Lane.  However, by 1851 the name Newbould & Baildon had been adopted.  At the Great Exhibition in that year, the firm received an Honourable Mention.  It exhibited:

Specimens of Roberts’ patent table-cutlery.  The blades are fastened by means of a dovetail without cement, and cannot be injured by hot water.  Specimens of registered ivory-handled table-knives.  The tangs are made square, and nicely fitted into the handles, without cement, and riveted through at the extremity.  Specimens of table-knives with silver handles.

The firm was dissolved in 1852.  Newbould Bros, which featured William, later operated from the same address in Eyre Lane.  In 1854, Joseph Baildon announced his departure from Sheffield with a sale of his household furniture.  He moved to Newcastle-under-Lyme, Staffordshire, where he prospered as an ironmonger.  He became Alderman and Mayor, before retiring to Southport, where he died on 2 January 1881.
