STOP GUESSING!
You are wasting everyones's time.
Copper is a soft metal compared to steel.
Clearly you have the wrong tool for the job.
I dont know what the right tool is.
Like everyone here I am looking for the answer and not finding it.
STOP GUESSING!
Let someone who knows answer it instead of adding to the confusion.
