For those born sans silver spoon, the unexpected career path of the unassuming Harry Brearley saved them from unhygienic rusty forks, plastic knives and the unbearable thought of doing away with cutlery altogether.

He had less-than-average schooling (‘never clamoured for more’), but became fascinated with watching metal-workers, including his father, crafting their wares.

The 12-year-old, however, was ‘too frail’ for such an industry, so became a bottle washer at a chemist’s laboratory, where the chief chemist provided mathematical books to pass the time. Brearley enrolled at night school, attacking (academically) ‘one steelmaking interest after another’. In 1902, he published the 600-plus-page The Analysis of Steelworks Materials , which he had written in eight weeks, leaving him exhausted, but triumphant, ‘as a woman must feel after giving birth’.

As a recognised metallurgist and analytical chemist, he was tasked with investigating the erosion of rifle barrels at the Royal Arms Munitions factory in 1912. Brearley began testing alternative steels using chromium and, by 1913, the first ‘rustless steel’ was melted. He suggested using it for cutlery — Sheffield had been the centre of the industry for more than 300 years — but cutlers found the metal too hard and thought it abhorrent that households would no lo.
