A handheld lever and fulcrum device designed to maximize squeezing is often referred to as a lever-based squeeze tool or a hydraulic press. It utilizes the principles of leverage to amplify the force applied by the user, allowing for greater squeezing power with less effort. This type of device is commonly used in various applications, such as juicing fruits or compressing materials, by enabling the user to exert more pressure efficiently. The design typically features a handle, a lever arm, and a fulcrum point that optimizes the mechanical advantage.
A fulcrum in a lever is very important because without a fulcrum a lever isn't a lever , and the fulcrum is the main part of a lever.
The fixed point of a lever is called the fulcrum. A lever is a beam connected by a hinge, or pivot, called a fulcrum. A lever is used to amplify the applied force.

A lever pivots on its fulcrum, which is the fixed point where the lever rotates. The position of the fulcrum affects the mechanical advantage and function of the lever.
The fulcrum. A Lever is a rigid rod to which a force can be applied to overcome a resistance. The point at which a lever pivots is called the fulcrum.

Sugar tongs are an example of a class 2 lever. In this type of lever, the load is between the fulcrum and the effort. When using sugar tongs, the sugar acts as the load, the pivot point where the tongs are squeezed together acts as the fulcrum, and the effort is applied by squeezing the tongs to pick up the sugar.
A forceps belongs to the class of levers known as a third-class lever, where the effort force is between the fulcrum and the load. In forceps, the hand squeezing the handles provides the effort force, the load is the object being grasped, and the pivot point acts as the fulcrum.

The class of a lever is determined by the relative positions of the fulcrum, load, and effort. In a first-class lever, the fulcrum is between the load and effort; in a second-class lever, the load is between the fulcrum and effort; in a third-class lever, the effort is between the fulcrum and load.
