Re: bending a new hook on a spring

Neither. It's spring steel, so it'll spring back.

Kidding aside, it depends largely on how you bend it. If you were to bend it without heating, I'd put the odds of reduced life pretty high--but it's not as likely to break as you might think. But that bend isn't going to be easy without heat. Heating... well, I think you're as well aware as I am that heating isn't going to leave the desirable properties of the material alone.

And then you have the additional headache: is the reduced length going to cause extra tension in the system that the spring goes into?
