I was at an antique store today and found a fountain pen. I had heard of Waterman pens and as it was brand new, with a cartridge, and with the converter for $20, I figured I couldn't go too wrong. When I got home, I did some research and I think this model is called the Phileas, but I'm not positive on that. It has a fine nib, which is still much broader than what I'm accustomed to (Pilot G2 .38). Out of curiosity I thought I'd try writing with the pen upside down to see what would happen. By upside down I mean just rotating the pen in my hand 180 degrees so that the engraved portion of the nib is facing the paper. To my surprise, the line was much, much thinner and suddenly became more than tolerable. It doesn't seem to skip or start slowly. But ... is it bad for the pen or the nib to write upside down? As this is my first pen, I really have no idea. Any advice would be welcome.
