IN A WORLD WITHOUT CASTINGS Would Cutting Be a Cinch?


Evidence of rudimentary scissors


can found as far back as 1,500 BC around Mesopotamia and Egypt. Te cast bronze model shown to the left (circa 150 AD Turkey) required a lot of pressure near the C-shaped curvature to push the two blades past one another. Te exact origins of scissors with


two shears bolted together are not known, but the technological advance- ment that made them a household item can be pegged to 1761. Robert Hinchcliffe of London cast the two parts in stainless steel—a process that allowed mass production of sharp, durable blades. Te majority of today’s scissors


continue to be steel, though many are produced via forging and stamping in addition to casting.
