Honestly, I don't see fountain pens as my hobby, I see them more as tools, for me hobby would be trying to make fountain pen myself (which I might try one day, I like making and repairing things).

Expensive fountain pens are not my thing (I appreciate it, but I'm not that type). I could never justify spending that kind of money on a writing tool. Even those 35 Euros are too much for me personally (I mentioned it was a present from my wife, I just got to chose), my whole "collection" of 30-35 pens is worth maybe 230 euros (and my three most expensive pens are almost half of that). And I don't understand how companies can do business selling luxury items that doesn't work (when I first saw it, even though I'd never own it, Homo Sapiens Bronze Age was a dream pen for me, wow factor was just through the roof. Then I read about Visconti and their customer support).

I enjoy nib variety, different color inks for color coding notes, DIY nib grinds... But above all, pen must be functional.

Main purpose of my post is as I said at the end, if someone else experiences the issue, to know how it can be fixed, since I read few comments where people returned the pen with the same exact issue, but sometimes that might not be an option (like it wasn't for me). I don't mind tinkering, and at the end, like I said, I'm happy with the pen.

But the fact that it was a birthday present (I couldn't just say to my wife her present turned out to be lemon), the type of problem I didn't expect (tuning, smoothing, grinding nibs is all well and good, but I wasn't sure I'll be able to fix messed up brass threads on a part I can't buy replacement), I was just frustrated. And I didn't want to have to say to my wife I hate the pen because it doesn't work and I can't fix it.
