These pliers are used for extracting deep embedded nails from timber or removing objects out of a material that they have been previously applied to. Also suitable for extracting nails from concrete. Ideal for the builder, DIY, construction and handyman use. 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.
