What you are saying is right.....
All I'm saying is that a paper clip can be used as a spring, but it would be a very poor one, even if used BELOW yield stress like a magazine spring. So could a spoon, or a screwdriver. Other metals have the same properties as spring steel but in vastly different degrees.
The paper clip/magazine spring analogy is entirely irrelevant and wrong because if you don't bend the paper clip -- but bending the paper clip is the premise in this irrelevant analogy-- you will not exceed the yield stress of the clip and thus will hardly likely fracture the paper clip. Sure, substantially exceeding yield stress will fracture solid metal -- but this is NOT the mode of failure in magazine springs which operate BELOW yield stress.
