It depends on which side of the hammer you're using. If you're using the claw part its a class-1 lever, but if you're using the hammer itself, it's a class-3 lever.

A hammer is a class 2 lever
A hammer is a class 3 lever. The force, your muscle, is between the fulcrum, your elbow, and the load, the hammer.
It is like scissors, a first class lever.
The lever class of a hammer depends upon its use. If the hammer is used as a claw to remove a nail, it is a first class lever. When the hammer is used to strike a nail, it is a third class lever. There are three classes of levers. The difference between the classes lies in the position of the load, the effort and the fulcrum. When the fulcrum is between the load and effort, the object is a first class lever. If the load is between the fulcrum and effort, the object is a second class lever. A third class lever places the effort between the load and the fulcrum.
A crane is a first class lever when it is winching in or out the rope attached to a load. The crane becomes 3rd class lever when it's boom is luffing, i.e. it is being lowererd or raised.
A hammer is a 3rd class lever. A third class lever has a load-effort-fulcrum configuration. What is interesting about a hammer is that though the load is the head of the hammer, the effort and the fulcrum are both in the hand. What makes it a 3rd class lever is that the effort is more in the hand and fingers, while the fulcrum is closer to the base of the hand at the wrist.
Yes, a claw hammer is a first-class lever because the fulcrum (pivot point) is between the effort (force applied to the handle) and the load (the nail being pulled out or hammered in).

A hammer can be considered a first-class lever when the fulcrum is placed at one end, with the effort applied at the other end to overcome a resistance in the middle. It can also be viewed as a second-class lever when the fulcrum is at one end, effort is applied at the other end, and the resistance is in between. In practical terms, a hammer's functionality aligns more closely with a second-class lever due to the positioning of the hand as the effort, with the nail acting as the resistance in the middle.
Yes, a trolley is considered a second class lever. A hammer is considered a third class lever. Also, a clothes pin is considered a third class lever.
