Pen Review: Revisiting the Pilot FA Nib, This Time on the Pilot Custom 743 Verdigris Green

May 6, 2026

Back in 2017, I reviewed Pilot’s FA nib on the Custom 912 fountain pen, and while I came away from that experience impressed with the amount of flex that the nib offered, I couldn’t use it as an everyday writer. Personally, I’ve never “chased flex” in fountain pens - either vintage or modern - as I’m not a calligrapher and I don’t typically draw or otherwise practice lettering. That said, I do occasionally enjoy a soft fountain pen nib, such as when I want to journal in cursive or explore different inks. I’ve already written about how much I enjoy the soft fine-medium from this year’s Custom 74 “Lavender Fog” North American Exclusive, and I’ve also come to appreciate the FA nib on the larger Custom 743.

Pilot Custom 743 vs. Pilot Custom 912: Not the Same Nib

But isn’t Pilot’s FA nib the same on either pen? No. When we hosted our unfortunately-weather-abbreviated store event back in January, I had the opportunity to compare the FA nibs on the Custom 912 and Custom 743 side-by-side. Those who prefer a much softer and wetter writing experience closer to a true flex nib should opt for the Custom 912, whereas those who - like me - do more standard writing should probably choose the Custom 743. The two pens have different nibs, with the Custom 743 featuring a stiffer nib that also appears on the Pilot Custom 823.

The top writing sample (in Sailor Ink Studio 670) was done with the Pilot Custom 743 FA nib. The bottom writing sample was done with a Custom 74 Lavender Fog with a Soft Fine Medium (SFM) nib, in Tono & Lims Deep Field Laniakea.

What I Enjoy About My FA Nib and How I Use It

I chose this pen, and the FA nib in particular, for several reasons. First of all, this Pilot Custom 743 is a North American exclusive in Verdigris Green, and I wanted to be sure to get one before they are inevitably discontinued. In my mind, this special pen needed a fun nib, and after trying the Custom 743 version of the FA, I knew that I’d be able to use it regularly, even if not as an everyday writer. I’ve had this pen inked for two months, and here’s how I’ve put it to work:

  • Handwriting Improvement. One of this year's goals is to practice my cursive whenever I can, and it’s much more fun to do that with a nib that has some bounce to it and offers good line variation. With just light pressure, you can vary the line width of your up- and down-strokes, though I can’t overemphasize that like the “soft” nibs on the Pilot Custom 74, the FA nib should not be overflexed. It is possible to spring these nibs and cause irreparable damage. While I’ve not done any sort of scientific measurement, I would estimate that you can safely vary the line width on this pen 2-3 nib sizes (i.e., extra-fine to medium, or fine to broad).

  • Exploring Ink. The other benefit to line variation is that it can bring out the special properties in fountain pen ink, especially shading and shimmer. I’ve never focused as much on ink as I have on pens and paper, but since I receive more questions on ink these days (particularly in-store), I’ve felt the need to broaden base of knowledge on how different inks work in different pens, and with different pen and paper combinations.

  • Testing Paper. Similarly, in my line of work I need to know what kind of paper holds up well to wetter nibs, and how far I can push certain papers to the point where they will start to feather or bleed. You can really test just how “fountain pen friendly” certain paper is by pairing wet inks with soft nibs, even if sometimes the point of failure is well past what most people require for everyday use.

Chasing Nibs and Not Necessarily Pens

I remarked in last week’s post that over time, the focus of my pen use/collecting has reoriented towards nibs rather than pens. Sure, it’s fun to collect a new custom material or a favorite model in a new color, but most of my personal purchases over the past two years have been driven by whether the nib offers a unique writing experience. My current collecting “grail” is to fill out a set of all the Pilot specialty nibs over time, in unique pens if possible. Recently I’ve added the FA pictured here, and I’ve also been loving the WA (Waverly) nib as a smooth everyday writer. Just wait until you read the recap from my upcoming trip to Japan, because this collection is about to get a lot bigger. :)

Pen Review: Pilot Custom 912 with FA Nib

March 8, 2017

The Pilot Custom 912 is one of those fountain pens that's attractive in that distinguished "black pen with rhodium trim" kind of way, but it's main purpose is to act as the showpiece for Pilot's specialty nibs, including the stub (SU), the Waverly (WA), Posting (PO), Music, Soft Fine (SF), and the Falcon (FA) nibs. The pen featured in this review sports Pilot's semi-flex Falcon (FA) nib, which is the first that I've had the opportunity to try for an extended period of time. While I can see why many people really like this nib, it doesn't work so much for my personal handwriting style.  

Note the "wings" cut out of the sides of the nib, which adds to the springiness of the nib. As with the Pilot Custom 74 and the Pilot Custom 823, Pilot adds a nice engraving to the Rhodium cap band.

Build

The Pilot Custom 912 is a sturdy, well-built pen that could easily serve as your daily driver (provided, of course, you find a nib that works for your writing style). It's on the larger side (5.5 inches unposted and 6.25 inches posted), but still fits very comfortably in the hand. The Custom 912 uses Pilot's Con-70 high capacity pump-style converter, which is the same one that comes with the Custom 74 and which I always enjoy. The barrel is made of black resin, and since the pen is a cartridge-converter filler, it's a light pen, making it suitable for longer writing sessions (again, assuming you have the appropriate nib). Rhodium plated trim and a 14k gold nib lend a classic look, if a somewhat unexciting one.

The Pilot Falcon (FA) Semi-Flex Nib

The nib is plainly intended to be the star of the show on the Custom 912. I wrote with a Pilot Metal Falcon many years ago, and wasn't blown away. For whatever reason, my print-cursive hybrid style of handwriting doesn't lend itself to the Falcon/FA nib's flex.  (To be more accurate, I should say semi-flex - the FA nib is not a "flex nib" in the vintage sense, but it's more than just "springy"). As you can see below, you can coax some very nice line variation out of this nib, but I didn't find it to be the smoothest writing experience when printing, as opposed to writing cursive. This past weekend I had the opportunity to test drive Aurora's new vintage-style flex nib, which, in my opinion, seems more versatile in terms of easily switching between cursive and script. I should have a review of that nib up on the blog in the near future.

Takeaways and Where to Buy

I will definitely purchase a Custom 912 at some point, but it probably won't be a model with the Pilot FA nib. This past weekend I also had the chance to write the Pilot's PO nib, a super-stiff, extra-fine Japan-only specialty nib that would probably be my first choice. (NOTE: being able to test rare and hard-to-find nibs is one of the many benefits of visiting pen shows!) That said, I know many people who enjoy writing with flex and semi-flex pens who love the Pilot FA nib and can make it do wonderful things with their handwriting.  

As of 2026, we carry the Pilot Custom 912 as a regular item in our own shop. The Custom 912 comes with standard and specialty nib options, including Extra Fine, Soft Fine, Stub, Music, PO (Posting), Falcon (FA), and Waverly nibs, with offering changing depending on pricing and availability. Since this review was first published, Pilot has worked to expand their specialty nib offerings stateside, and we are happy to carry many of them in both the Custom 912 and Custom 743 sizes.
