A brief history of concretor’s nippers and pliers

Concretor's nippers being used to twist wire around rebar steel reinforcement used in concrete. The origins of concretor’s nippers and pliers can be traced back to the end of the 19th century, shortly after reinforced concrete building techniques began to be used. .
The Flaxmill in Shrewsbury was the worlds first iron framed building built in 1797. Although there were some earlier buildings, such as the world’s first iron framed building the Flaxmill in Shrewsbury, built in 1797, which used metal in their structure, and later ones made with steel reinforced concrete, these did not use twisted steel bars tied together to provide reinforcement to the concrete.
The worlds tallest building is currently the Burj khalifa Englishman Ernest L. Ransome was the first to use this technique when he designed two San Francisco bridges in 1886. Steel reinforced concrete that uses steel twisted bars has since been used in many buildings and structures and is probably most famous for its use in the construction of skyscrapers.
Tools used before concretor's nippers and pliers were developed included pliers and end cutting pincers. When steel rebar was first twisted and tied together as reinforcement for concrete, tools such as pliers  and end cutting pincers were used to twist and cut the wire that held the rebar together.
Concretor's nippers being used to twist wire around rebar steel reinforcement used in concrete. As the use of steel reinforced concrete grew and so the practice of tying rebar together increased, these tools were adapted to make the job of twisting and cutting the wire quicker and easier, and so the concretor’s nippers and pliers were developed.
