A claw hammer is classified as a type of third-class lever. In a third-class lever, the effort is applied between the load and the fulcrum. When using a claw hammer to pull a nail, the fulcrum is typically located near the end of the hammer's handle (the portion you grip), the load is the nail being pulled, and the effort is applied at the handle to lift the nail.
