Back in 2003, just after I bought my red Parker Vector pen (a decent pen for a student), I bought a blue Parker Reflex (which is no longer in production, though you can still find them). From day one, it didn't work. It either flooded or skipped, depending on the angle I held it, and the letter I was trying to write at the time.
I very sadly put it away, since it was precisely my favorite shade of blue.
Fast forward twelve years. I spotted the problem with the pen last week: the tines were uneven. Not crooked--the feed slit in the nib was cut unevenly. One tine was shorter and much narrower than the other.
So, I started trying to figure out if I could replace the nib--hard to say, because I cannot figure out the size of nib I need. I know more than I used to, but I'm still far more novice than expert. I did get the nib and feeder* removed and got a better look at the problem, today.
And then, I fixed it. It's a cheap, soft stainless steel nib--nothing high quality, but utilitarian, when it works--so I took an emery board to it, and evened up the tines, then put it back. Inserted a cartridge, and tried it out.
It works. For the first time since I bought it, it neither floods nor skips.
Best of all? I much prefer a fine nib to the medium it came with, and after the work I did evening up the tines on the nib, it's now more fine than medium.
*The feeder is the plastic thing behind the metal that makes up the nib.
