Tweezers are typically considered to be Class 1 levers, where the fulcrum is located between the effort (your hand) and the load (item being picked up). This allows for precise and controlled movements when grasping small objects.
They are both compound 3rd Class levers. The fulcrum is the bit which is stuck together, the Effort is where you press them to make them work, so in the middle, and the load is at the end of the tweezers/nail clippers where you make the magic happen :)
Tweezers are an example of a third-class lever, where the effort is applied in between the fulcrum (pivot point) and the load (object being lifted). In tweezers, the hand applies force between the pivot point and the object being grasped.
Yes, tweezers can be considered a type of lever. When you squeeze the ends of the tweezers together, you are applying a force at one end to create a movement at the other end, similar to how a lever operates.
A pair of tweezers is a third-class lever because the effort (force applied by your fingers) is between the fulcrum (the pivot point) and the load (the object being lifted or squeezed). This arrangement allows for greater precision and control. Third-class levers are common in tools that require accurate manipulation of small objects.
The mechanical advantage of a third-class lever is always less than 1, meaning that the output force is greater than the input force. Third-class levers are designed to increase speed or range of motion rather than force. Examples of third-class levers include tweezers and forearm muscles.

A class three lever is where the load is one side of the force and the fulcrum is on the other side of the force. An example is a pair of tweezers. Another example is the secondary lever in a pair of fingernail clips, i.e. the part that closes on the fingernail. (The first lever in a pair of fingernail clips, i.e. the part that you press on, is an example of a second class lever.)

The three types of levers are first-class, second-class, and third-class levers. In a first-class lever, the fulcrum is positioned between the effort and the load, like a seesaw. A second-class lever has the load between the fulcrum and the effort, such as a wheelbarrow. In a third-class lever, the effort is applied between the fulcrum and the load, exemplified by a pair of tweezers.
The mechanical advantage of a third-class lever is always less than 1, meaning that the output force is greater than the input force. Third-class levers are designed to increase speed or range of motion rather than force. Examples of third-class levers include tweezers and forearm muscles.
Class-I . . . Effort and resistance on opposite sides of the fulcrum. Class-II . . . Both on the same side of the pivot, resistance closer to it. Class-III . . . Both on the same side of the pivot, effort closer to it.
