Although every fountain pen manufacturer for the past 100 years has made specialized nibs for almost every occasion, only Esterbrook and Pelikan have made it easy to exchange nibs on one pen you already love.
Both companies have made simple complete nib unit assemblies that are easily screwed into and out of the section (grip) of every one of their fountain pens. Esterbrook was the most famous for doing this in the United States from the 1940s into the 1960s. Their line up of nibs included dozens of different sizes and strengths for different jobs.
Whether you wanted to switch from a fine point to a stub for caligraphy or you stabbed your nib into the desk top out of anger or frustration, all you had to do was unscrew the old nib and replace it with a new one.
Each Esterbrook nib had a model number that indicated what type of nib it was. A 1550 was an extra fine “Durachrome” (aka thin steel) nib intended for bookkeeping. A 9314F was a “Master Durachrome” (aka a much thicker smoother writing steel) nib that wrote a fine stub line for a fancy writing effect or caligraphy.
The 9000 series of Master Durachrome nibs was the very best Esterbrook had to offer, and now we offer nearly 100 replacement nibs spanning 7 different models on our Inkwells & Blotters pages. We only show 1 of each of the 7 different models, but you can order several of each.
These 9000 series nibs are getting increasingly rare. Once we run out, we don’t know how soon we will be able to find more.
