Pivoted scissors were not manufactured in large numbers until 1761, when Robert Hinchliffe of Sheffield, England, began using cast steel to make them. Cast steel, recently invented at the time by Benjamin Huntsman, also of Sheffield, was made by melting steel in clay crucibles and pouring it into molds. This resulted in a more uniform steel with fewer impurities.

An immense stride in perfecting scissors was taken in 176I,
when on Robert Hinchliffe produced the first pair made of
cast steel, hardened and polished. The story is that love
stimulated his inventive genius, and that his efforts were
inspired by desire to win the affections of a young woman
whom he wished to take for wife. The forming of the bows
was his greatest difficulty. His first method was to make them
solid; then drilling a hole, he enlarged this to the required size
by laboriously filing away the metal. Afterwards he hit upon
a simpler plan, and a ready sale was found for his wares in
London and other markets. He lived in Cheney Square, and
was reputed to be the first person who put out a signboard
proclaiming himself " fine scissor manufacturer. '
