I grew up (active in the shops from 8+years old) in top-shelf auto restoration shops, doing full-kit jobs on best-placing Concours show cars.

I've seen a lot of fine metal beaten in every conceivable direction -- with every imaginable kind of hammer...

...which brings the hammer to the conversation.
The hammer I'm speaking of here/now is the bullet.

Anyone here ever own a vintage Ferrari?
Do y'all know what the tool kit looks like for a top shelf street roadster?
One thing you'll see in there is a big lead hammer.
That big lead hammer is your lug-wrench for wheel removal/replacement.
That big lead hammer is what the factory prescribes as the ideal tool for knocking the knockoff (single central) wheel nuts loose.

Try the same operation with a hard copper or cupric alloy wrench, and you'll likely end up screwing up the finish on the spinner nuts.

Could it be possible that this dead VS springy nature of the bullet material could have something to do with the phenomenon?

Just thinking...
