A third class lever is a lever where the force is applied between the fulcrum and the load. A fishing rod is a third class lever if it is fixed at the base and the hand holding the rod is between that fulcrum and the other end of the rod. It is also a third class lever by extension of your arm, wherein the fulcrum is your elbow and the force is your biceps or triceps muscle, which attaches close to that fulcrum.
In a limiting case, a fishing rod is a first class lever if it is supported between the ends and you hold it at a point beyond that fixed fulcrum. This is not common, I think.
'Mechanical Advantage' of a 3rd class lever is always less than 1. Force on the resistance is less than the effort force. Distance moved by the load is greater than distance moved by the effort. Eg: fishing pole.
A hairbrush is a third-class lever, where the force is applied between the fulcrum (pivot point) and the load (hair being brushed).
wedgeA fishing pole is made up of 3 simple machines, it is a 3rd class lever, a pulley and a wheel and axle which is your reel.
Ice tongs are actually third class lever. In a third class lever, the effort is between the fulcrum and the load.
No, a knife is not a 1st class lever. A 1st class lever is a system where the fulcrum is positioned between the effort and the load. In the case of a knife, it typically functions more like a 3rd class lever where the effort is between the fulcrum and the load, such as when cutting through food.

The answer to the question is: "No." A shock absorber is not a lever at all.
It is 3rd class.

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.
