Esterbrook nibs

Image of Renew-Point nibs[ | ]

Unlike the earlier dip pens, whose nibs could generally be interchanged in a moment, fountain pens usually had a nib/section assembly that made changing nibs a job for a professional. A few companies devised schemes using nibs that were pressed or molded together with their matching feed units and then threaded as an assembly into the pen’s section. Among vintage makers, Esterbrook, with its “Re-New-Point” design (U.S. Patent No 1, 918, 239, by Leon H. Ashmore), was perhaps the most successful of the vintage American companies. At various times, Re-New-Point nibs (later renamed Renew-Point) were available in 33 styles. The standard Renew-Point was the Duracrome series. For a short period beginning in late 1938, Esterbrook also produced the 3xxx series of Osmiridium Tip nibs; these nibs have a very attractive sunburst design. (There also exist certain 3xxx nibs that are gold plated and lack the sunburst imprint.) Production of 9000-series Master Series nibs began in 1940; like the 3xxx, these nibs were tipped with osmiridium and provided better performance and durability than the standard nibs.Fountain pen During the Second World War, Esterbrook made 8000-series nibs of 12K palladium alloy to conserve critical war resources.

The Wahl Personal-Point system (from the 1920s) and Sheaffer’s Fineline pens (from the 1940s and ’50s) used unique designs; but Osmiroid, Tuckersharpe, and some Venus pens could accept Esterbrook Renew-Point nibs. Venus even packaged its nibs in boxes bearing the words “Standard Thread.” The pen illustrated here, a Tuckersharpe, is interesting because of its transparent section and nib assembly.

Today, the most prominent maker of user-interchangeable nibs is Pelikan; but Pelikan’s nibs come in several sizes to fit different pen models, and not all sizes are interchangeable.

The table below lists all the known Renew-Point nibs.


  1. Early 5000- and 7000-series Dip-Less nibs are technically not Renew-Point nibs; they slip with a mating feed into a threaded socket (which can accept either these nibs or Renew-Points) and are locked in place. I include the 5000 and 7000 series here because they bear 4-digit numbers and are contemporaneous with the Renew-Point. (Later versions of these series are Renew-Point interchangeable.) The photos of feeds shown here have been retouched to show the feeds’ features more clearly.
  2. As illustrated here by an 8440, 8000-series specimens exist with a gold-plated variant of the 3000-style Sunburst design. I have no information on why these unusual and very attractive nibs were given numbers in the 8000 series.
