I wondered if that might be the case, but I don't know how it would have happened. I found the nib on the floor, but I think if I'd stepped on that wouldn't be the only problem! Is there a good way to bend them in to tighten the nib.
I'm always reticent about posting advice about any kind of nib work. However, since Lamy nibs are so inexpensive and ubiquitous, I'll make an exception (I'm kind of cringing as I write this, because I don't want anyone to damage their nibs).
In any case: about a year ago, this very thing happened to me, while I was in a pen store, in fact. The nib slid right off the pen (it was an Al-Star). The man behind the counter, a fixture in Toronto pen circles, with many years experience, and someone I trust -- he'd tuned several of my more expensive nibs -- said "I can fix that for you".
I handed him the nib and the pen. This is what he did:
- placed the nib on the glass countertop, face up (ie: so that you can see the breather hole and read "lamy" on the nib).
- grasped the two sides of the nib with his thumb and forefinger. Firmly.
- using the index finger of his other hand, he pressed down on the top of the nib. Even pressure across the whole surface. Gradually building up pressure. But not too much.
In effect, he was forcing the underside of the nib to bend upward.
That was it. He slid it back on the pen and it stuck there. Next time I had to remove it to clean the feed, I needed to use tape to pull it off.
That said, just this past week I've noticed it loosening up a bit.
Again, if you're going to try this, a) hold the nib firmly so that it doesn't shoot across the room when you press on it, and b ) caveat emptor. I know the lamy nibs are inexpensive, but no one wants to damage their nib (especially these days when it's not as easy as usual to restock).
