Yes since they are a example of levers having Fulcrum in between Effort and Load, hence by applying small force/effort considerable amount of work can be performed.

Pliers are tools that allow you to exert a greater force with increased precision compared to using your hands alone. They utilize leverage to make it easier to grip, twist, or cut objects, making them force multipliers rather than magnifiers.
Pliers can act as a force multiplier by increasing the force applied to an object. They can also increase the accuracy of gripping and manipulating objects by providing leverage, but they themselves do not magnify the distance of the force applied.
Pliers increase the applied force by using leverage. When you squeeze the handles, the jaws of the pliers multiply the force you apply, allowing you to grip and manipulate objects more easily. This makes it easier to hold, twist, or cut objects without having to exert as much physical effort.
In a pair of pliers, the fulcrum is the pivot point where the two handles meet. This allows the user to apply force on one end of the tool while the jaws exert a different force on the other end. The position and design of the fulcrum determine the mechanical advantage of the pliers.
The principal magnifiers are the microscope and the telescope. Microscopes are used to magnify small objects, such as cells or microorganisms, while telescopes are used to magnify distant objects, such as stars and planets. Both magnifiers use lenses to enhance the visibility of objects beyond the naked eye's capabilities.
A pair of pliers is a type of lever, specifically a class 1 lever, where the pivot point is located between the effort and the load. When you squeeze the handles of the pliers, it creates a mechanical advantage by allowing you to exert a greater force on an object with less effort.
