Concretor’s nippers and pliers use their long handles pivoting around the pivot bolt to create a large leverage force at the jaws’ cutting edge. When applied to the small area of the cutting edge, this large force enables them to cut through wire and nails.
How do levers work?
Levers use a mathematical principle known in physics as the law of the lever to multiply a user’s input force at the output of the lever.
The further from the pivot point the user applies pressure on the handles and the closer the jaws are to the pivot point, the greater the output force will be at the jaws.
High leverage concretor’s nippers and pliers have longer handles allowing you to apply the input force at a greater distance from the pivot point. They also have jaws that are shorter and closer to the pivot point. This greatly increases the output force at the cutting edge of the jaws. One manufacturer claims its high leverage concretor’s nippers and pliers require 25% less effort or input force from the user than similarly sized pliers.
Why are concretor’s nippers and pliers hardened?
Like any tool designed for cutting, concretor’s nippers and pliers have to be made of a harder material than the object they are cutting. Concretor’s nippers and pliers are made of steel which is already a hard material, but as nails and wire can also be made of steel the nippers and pliers have to be further hardened.
