It is most likely that scissors were invented in 1500 BC in ancient Egypt.[1] These were likely shears with the joint at the far end.[2] Cross-bladed scissors were invented by Romans around AD 100.

An immense stride in perfecting scissors was taken in 1761 when Robert Hinchliffe produced the first pair of modern-day scissors made of hardened and polished cast steel. He lived in Cheney Square, London and was reputed to be the first person who put out a signboard proclaiming himself "fine scissor manufacturer".[3]

In a part of Sweden (now in Finland) an ironworks was started 1649 in the hamlet "Fiskars" between Helsinki and Turku. In 1830 a new owner started the first cutlery works in Finland, making among others scissors with the trade mark Fiskars. Fiskars Corporation introduced new methods in the manufacturing of scissors in 1967.[4]
