Pincers are a hand tool used in many situations where a mechanical advantage is required to pinch, cut or pull an object.
Pincers are first-class levers, but differ from pliers in that the concentration of force is either to a point, or to an edge perpendicular to the length of the tool.
Sharpened pincers are also used to cut away natural calluses, also called chestnuts, from a horses body.
They're often used in jewelry making, for trimming flat wire or cutting off the end of an ear stud.
Pliers are a similar tool with a different type of head used for squeezing, rather than cutting and pulling.
