Yes, a hammer can be both a class-1 and a class-3 lever. Although, not all levers can be more than one class only some. For example, a hammer and a clothespin.
In third class levers effort P is in between the fulcrum F and the load W. According to the principle of lever, W/P = effort arm/load arm, here effort arm is always less than load arm.Therefore more effort has to be applied to overcome a small load. Example:- forearm used for lifting a load on the palm.
This isn't that kind of carjack that you guys think it is, it a kind of tool for a car. It makes work easier because you can use it as a lever. You can use it as any kind of lever, a first class lever, a second class lever, ora third class lever. It works better as a third class lever. It works better as a third class lever because your using less work. Less work is being done with a third class lever because of he distance. The more the distance, the less force you need. Also, the more the distance, the less heavier it is.
In a third class lever the input force is located between the output force and the fulcrum.
Body has got third class levers in most of the places. This is why you can move the objects to larger distance at the cost of more power.

disadvantage of first class the fulcrum lies on more effort or more force.
Class-III Lever . . . MA always less than 1. Class-II Lever. . . . MA always more than 1. Class-I Lever . . . . MA can be 1, more than 1, or less than 1.

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.
disadvantage of first class the fulcrum lies on more effort or more force.
