If you misuse a tool, and the tool performs poorly at the job it's not designed for, but never fails in an unexpected way, and still maintains all the functionality it always had, how have you broken that tool?

If try to hammer in a nail with the butt of a screwdriver, and make a complete pigs ear of it, but the screwdriver absorbs the abuse and is still perfectly usable as a screwdriver afterwards, did I "break" the screwdriver?

Or, am I misunderstanding how the word "breaking" is being used here? Is there a meaning I'm not getting?
