This business was launched by George Clarke Shore, who was born in Gainsborough, Lincolnshire, in about 1805.  He was listed in Sheffield in 1841 as a commercial traveller.  By 1845, he was described as a cutlery merchant and manufacturer, Broom Parade.  By then, he had joined Joseph Fenton to establish Fenton & Shore – the forerunner of Joseph Fenton & Sons.  In 1857, the partnership with Fenton was dissolved.  Shore & Bagshaw then appeared (with Robert Bagshaw), but this was dissolved in 1859.  Shore decided to organise his own business (perhaps because his sons had come of age). 

A trade advertisement in 1860 described Shore & Son as a manufacturer of sportsman’s knives, pen, pocket, table, shoe and butchers’ knives, razors and scissors.  The firm was based in Eyre Street Works.  The trade mark was a set of dividers (picture) above the word ‘KEEP’ (apparently later acquired by Joseph Fenton).  Exhibition medallions for London (1851) and Paris (1855) grace the advertisement, but I have not found any evidence that this firm exhibited at either.  In 1862, Shore & Son was still listed, with George C. Shore and Gordon Shore (his son) residing at Sharrow View.  Apparently, George retired and moved with his son to Southwark, London, where George Gordon became a ‘collector’.  The father died in Fulham in 1883; the son at Poole Park, Fulham, on 2 June 1890, aged 52.
