Pilot Custom Heritage 912 vs Platinum President: The Ultra Fine Nib Showdown

Introduction

Some fountain pen buyers want color, flex, or flair. Others just want the thinnest, most precise line a nib can produce. That is exactly the territory these two Japanese pens occupy. The Pilot Custom Heritage 912 with a Posting nib and the Platinum President with an Ultra Extra Fine nib both aim for that micro-tip, gel-pen-like fineness, and both sit in a broadly similar price bracket. This comparison looks at how they differ, where each one excels, and which one is the safer first purchase.

Two Pens, One Question: Which Writes Finer?

The Pilot Custom Heritage 912 with the Posting nib is the newer arrival in this matchup, and its specialty grind immediately stood out during testing. Despite the name, the Posting nib is not about cap posting. It is a downturned nib that rides finer and firmer than a regular extra fine, almost like a needle point on the page. The 912 itself can be found for roughly $200 to $250, and sometimes less; one example was picked up for $185. Platinum’s Ultra Extra Fine nib is most commonly seen in the 3776, but it was also offered in the President, the step-up model above the 3776. Presidents have become harder to find and prices have crept up, typically landing around $250 to $280 depending on the nib.

Both pens are roughly the same size, use comparable large nibs, and are intended for the same kind of writing. That makes the differences in feel and line character all the more interesting.

The Nibs: Traditional Gold vs Downturned Tip

The Pilot’s Posting nib is a 14 karat gold, number 10 nib with rhodium plating. Pilot also offers it on the 742 if you prefer gold trim. The downturned shape is what gives it the finer, firmer ride.

The Platinum President’s Ultra Extra Fine is a different animal from the 3776 version. It is 18 karat gold instead of Platinum’s usual 14 karat, with a more rounded, traditional nib shape compared to the flatter 3776 profile. The Mount Fuji motif is still there. On the page, it stays firm in the Platinum style, but the 18 karat gold adds just a hair of bounce that the 14 karat nibs do not have.

How They Write: Line Width and Character

This is where the comparison gets genuinely interesting. The Platinum President’s Ultra Extra Fine has an architect-like quality: downstrokes come out beautifully thin, but cross strokes are noticeably broader, close to a full nib size up. It is smooth in every direction, writes plenty wet, and even with an ultra fine tip it can pull visible sheen out of a saturated ink. It carries the typical Platinum pencil-like feedback, but never tips into scratchiness.

The Pilot’s Posting nib writes the same width in every direction. Its upstrokes run a touch drier, a natural consequence of the downturned grind, but downstrokes, cross strokes, and figure eights all stay consistent. Where the two pens diverge is the cross strokes: the Posting nib stays thin there while the Platinum broadens out.

Put simply, despite the Ultra Extra Fine name, the Pilot’s Posting nib actually writes finer overall, at least against this President version of the Platinum nib. The 3776’s Ultra Extra Fine may be ground differently and could land closer, but against the President, the Pilot takes the crown for pure fineness.

Buying Advice: Which One Should You Choose?

If you have never tried either, the Platinum President Ultra Extra Fine is the safer blind buy. It is a traditional grind with a traditional feel, wet and smooth, and there is no specialty geometry you need to get comfortable with before spending $200 or more.

The Posting nib is the opposite. It is smooth and not scratchy, but you can feel it digging slightly into the paper, a deliberate resistance that some writers will love and others will not. It is best described as the fountain pen equivalent of a 0.3 mm gel pen. Blind buying one is not recommended.

The good news is that both are easy to test in person. Pilot and Platinum both exhibit at pen shows with their full nib lineups available to try before you commit.

Conclusion

Both pens deliver an exceptionally fine writing experience at a similar price, but they get there differently. The Platinum President offers a wet, smooth, architect-flavored ultra fine line in a increasingly scarce premium package. The Pilot Custom Heritage 912 with the Posting nib writes the finer line overall, with gel-pen precision and a distinctive tactile bite. If absolute fineness is the goal, the 912 wins; if you want a safer, more traditional ultra fine, the President is the one to hunt down, while stock lasts.
