I have a parker 45 fitted with an extra fine nib. While I was at work it rolled off my knee onto the floor, I am now starting to question whether its a rule that the rarer a nib is the more likely something is to go wrong as I've placed my TWSBI down in exactly the same way more time than I can count and it's never moved.
The nib shifted slightly but with very gentle pressure from my thumbnail, it went back into place.
Luckily I had brought my other 45 nibs into work with me to give them a dunk into some gold cleaner so I had something to compare it to.
Even before I put it back into place it continued to write fine and still does after however, I noticed that it occasionally clicks if my angle changes past a certain point while writing.
Now I am not 100% sure if it did click before the fall as I had only fitted the nib the day before and hadn't used it much. But I am wondering is it something that I should take steps to fix and if so what would be the best course of action. Or considering the fact that it writes fine should I just leave it be.
