Esterbrook 9128 Nib Comparison2009/06/01

Bottom line is Esterbrook fountain pens were made during the middle years of the 20th century and have held up very well. They come in a variety of colors, several sizes, and have easily swapped nibs. Since the nibs unscrew, Esties are extremely easy to clean even though they are lever-fillers. Pop out the nib and rinse. It’s as simple as that.
Here is what I discovered this week when I finally got my hands on another Estie and just happened to set up two 9128 flexible extra-fine nibs at the same time.
They truly are different. The nib used at the top has 9128 written across the nib while the second one has 9128 written down the length of it. No photos to show but the shape of the nibs is slightly different. The first one is slightly longer, more fine and has less flex catching occasionally on the upstroke. The second nib is closer to a fine with significantly more flex and somewhat smoother performance.
I thought I had a couple of oddball nibs but then I compared them to a third 9128 and discovered that the differences were consistent. The 9128 with the number across the nib is finer/stiffer and the 9128 with the number the length of the nib is thicker/more flexible. Laura (a/k/a Phthalo in the pen world) has found the same to be true with her Estie 9128 nibs.
So if you are looking for a really fine nib, the 9128 with the designation written across the nib is the one for you. If you want more flex and a slightly wider line, look for one with 9128 written down the length of the nib. Or you can do what I did. Get two Estie barrels and buy one of each style nib. It’s twice the fun. Promise!
