This pic doesn't help, Michael. the flesh /fabric wear has taken off the more powdery green sulfate patina to reveal the harder, brown patina. One is not looking at raw bronze in this photo.

I guess the point is that where there's contact, there's wear. The devil is in the proportions of wear shared by the two rubbing elements, the number of repetitions per unit time, both of which would determine how long it would take for significant wear to Proportions are based on hardness, but difficult to get a handle on in cases such as the Grand Canyon, or rubbing a penny on the carpet about half a million times to polish it. Bronze still trumps flesh, overall in the proportions, but I'll bet Victor's nub is actually worn down from its original, but we'd need a "before" shot to confirm this. But just think of how many, um, pieces of flesh have rubbed on this spot; or how much time it would have taken for one to do it!

So, as we've observed recently, please use a bore guide for any rod during scrubbing, at least!

Ben Franklin is supposed to have said that the shiniest key is the one that is used the most...
