I've heard of people removing their 'plates and breaking them in half with their hands. Easily.
I did exactly that with my headstay fitting. It looked O/K but had some brown staining so I buffed it up with my buffing wheels. It came up like chrome but there was a faint hairline scratch remaining - I buffed some more but it was still there. I took the whole fitting in my hands and tried to bend it whereupon it twisted like taffy and snapped through the hairline mark. I doubt it took 20 lbs of force to tear it in two and it had looked perfect - the hairline was nearly invisible.

At that point I pulled them all and made up new ones.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
