without castings IN A WORLD
Would Cutting Be a Cinch?
Evidence of rudimentary scissors
can be found as far back as 1,500 BC around Mesopotamia and Egypt. T e cast bronze model shown here (circa 150 AD Turkey) required a lot of pres- sure near the C-shaped curvature to push the two blades past one another. T e exact origins of scissors with two shears bolted together are not known, but the technological advancement that made them a household item can be pegged to 1761. Robert Hinchcliff e of London cast the two parts in steel—a process that allowed mass production of sharp, durable blades. T e majority of today’s scissors
are stainless steel, though many are produced via forging and stamping in addition to casting.
