Heh... I was going through a box of memorability and found a bunch of calligraphy "nibs" (I think they're called...).
I'm suddenly missing that "dip and draw" dynamic....
"Nib" is indeed the correct term. I don't have any dip pens, but I wish I did, as they are far easier to use than fountain pens. I *always* have a hard time getting fountain pens started.
