A twister is an example of a first-class lever, where the pivot point (fulcrum) is between the effort and the load. In a twister, the twisting force acts as the effort, the pivot point is the center of rotation, and the resulting motion applies a force on the load.

An axe is a type of lever known as a class 1 lever. In a class 1 lever, the fulcrum is located between the effort (in this case, your hand on the handle) and the load (the wood being chopped).
Scissors are typically classified as a type of double lever, where the two blades act as the lever arms with the pivot point being the screw that holds them together.
A ladle is a type of lever known as a class 3 lever. In this type of lever, the effort (force applied) is located between the fulcrum (pivot point) and the load (object being lifted). This allows for controlled pouring and scooping of liquids or other substances.
A spanner is a type of lever, specifically a class 1 lever. It helps to multiply the force applied in turning objects like nuts and bolts by increasing the length of the lever arm.
The elbow is a type of lever, specifically a third-class lever, that helps facilitate movement and provide mechanical advantage when bending or extending the arm.
