Exploring Custom Nibs: Custom Nib Studio "Perspective" Grind

June 11, 2022

When I was choosing pens to take on this latest trip, I leaned heavily towards loading up on specialty nib grinds that are an absolute joy to write with, because I really want to get some fun writing done. Whether that be journaling, a bit of “work” on the blog as opposed to the store, or simply playing around with pens, inks, and nibs, I feel like I haven’t had the chance to truly step away from the grind in a while. With that in mind, it’s a complete no-brainer that one of the pens I’d choose to take with me is my Pelikan M800 featuring the “Perspective” nib grind from Gena Salorino at Custom Nib Studio. Put simply, this nib is a joy to write with, whatever your specific use case.

This grind is a bit difficult to describe. Gena’s Perspective Nib combines the vertical/horizontal line variation of an architect with the variable line-width of a Naginata as you raise or lower the writing angle. It even writes an incredibly smooth XXF point on the reverse. The result might be the most versatile nib I’ve used. The standard writing angle can best be described as a forgiving medium architect, excellent for everyday writing because it omits sharp edges while still offering character and line variation. What sets this nib apart, however, is the fact that it can serve as an “all-in-one” workhorse. For example, I typically enjoy writing with a medium nib, but also need to be able to alternately write larger and smaller to highlight/underline and annotate, respectively. The Perspective lets you do it all with one pen.

One nib, four different writing options. The ink is Laban Poseidon Green.

From underneath, the Perspective grind appears almost wedge-shaped. You can see the tipping get wider, allowing you to write a wider line as you lower the angle.

I often talk about nib grinds as a way to salvage pens that you “like” but don’t “love”. Here, I asked Gena to modify the medium nib on my Pelikan M800 Stone Garden - a true workhorse pen that wrote too broad and wet a line for the type of writing I was doing. It bled through most of the paper used in my office (since we’ve recently cut costs even more and apparently gone even cheaper.) Paired with this grind, the M800 has arguably moved into my Top 5 Personal Pens, and I plan to send at least three more pens to Gena for the “Perspective” treatment.

Takeaways and Where to Buy

While you should absolutely take this glowing review with a grain of salt, since opinions on nib grinds reflect the personal preferences and use cases of the writer, the Perspective Nib from Custom Nib Studio is currently my favorite specialty nib grind. (I will say that everyone who has tried this nib - lefties included - has enjoyed it as well.) Fans of architect and Naginata-style nibs will certainly want to give this one a try.

If I’m working, and want to emphasize something that I wrote, it’s nice to be able to lower the angle for a bold underline.

The Perspective Grind costs $55. You can read more about this and other grinds Gena offers on the Custom Nib Studio website, or you can visit them at a pen show, where they’re regular attendees, though you’ll either want to take advantage of early sign-up prior to arrival at the show, or get there very early on show days for the best chance of getting a table slot.

Exploring Custom Nibs: Predator Hybrid by Mark Bacas

May 28, 2022

Late last year I embarked on what I expect to be a year-long experiment of comparing custom nibs available from the different nib grinders currently working, focusing on those grinds from each that can be considered a specialty or “signature”. Mark Bacas is one of the most experienced nib grinders out there, and whether you’re looking for a simple tuning or a more complex grind like the “Predator Hybrid” I’m discussing today, Mark will work with you to ensure the nib is ground to your personal preferences, and that you’re happy with the result.

So What the Heck is a “Predator Hybrid” Nib?

I can only assume that the “Predator” name draws its inspiration from the shape - pictured at the top - which resembles a bird’s beak. The “Predator Hybrid” nib is ground to an ultra-fine point on the normal side, with the reverse a wider, slightly brush-like medium. To compare, a “Predator Extreme” nib has the same ultra-fine point on the normal side, with the reverse ground to a full architect. You can read Mark’s own descriptions on these and other nib grinds he offers directly on his site. I would say that on this “Hybrid” version, the reverse is slightly softer than a full architect, while still offering a bit of the line variation you would expect from that grind.

Mark Bacas Predator Hybrid Nib Writing Sample — A writing sample showing the “normal” (i.e., nib down) width, compared against the reverse (i.e., nib upside down) width.

So in practice, how do I use this nib? If you’ve read my past pen reviews, you’ll know that I value pens I can use for annotation during my reading and research. This particular nib falls squarely into that category. The ultra-fine point accommodates my tiny handwriting and allows me to make even the smallest margin notes, while the reverse side is perfect for underlining, highlighting, and even standard writing. Frankly, I’ve never had a reversible nib write well to the point where I could use the reverse side for much more than a line or two. This one is smooth enough for standard writing.

TWSBI Diamond 580 Interchangeable Nibs — The TWSBI Diamond 580 Fountain Pen is one of many that features interchangeable nib units, so you can have multiple custom nibs ground to switch among your various TWSBI Pens.

Why I Love Interchangeable Nib Units for Custom Nib Work

For this grind, I chose to have Mark modify a TWSBI 580 medium nib unit, so that I can swap the nib between my various TWSBI Diamond 580 pens. Lately, wherever possible I’ve been having nib grinders modify interchangeable nib units from JoWo, Bock, and TWSBI so that their work isn’t tied to any particular pen. It’s quite helpful to be able to move the nibs around at times - some grinds are more suitable to different pens, depending on weight, balance, etc., and these threaded nib housings make swapping nibs a cinch.

Cost of Nib Modification - Cheaper Than Buying a New Pen

The grind featured here cost $50, and since I did not pay a rush fee, it took several weeks for Mark to turn around. (Mark is fast - some nib grinders take months, or even up to a year.) In response to posts like these, I often get the question: “Why pay extra money to ‘fix’ a pen that should write perfectly out of the box?” Here I think we need to break down the question a bit: Are you paying to fix a manufacturer’s flaw with the nib, in which case I absolutely agree with you that the cost of any repair should be born by the company that made the pen, or are you looking to personalize the pen for how you write? It should be fairly obvious that if you write extremely small, a standard stainless steel extra-fine nib may not be narrow enough for you, and you should consider a needlepoint or a nib like the Predator.

Mark Bacas Predator Hybrid Comparison — The “normal” point of the Predator nibs writes a ***very*** fine line, even finer than a needlepoint nib like the one ground by Kirk Speer (Pen Realm) for Esterbrook.

Even with standard nib widths, it’s impossible for a manufacturer to anticipate things like the amount of pressure you use and how you hold the pen. I have pens in my collection that, out of the box, wrote within “the range of reasonableness” and wouldn’t be considered defective, but still didn’t work for me until I had them tuned. I would estimate that 80-85% of the pens in my collection have been modified or tuned from “factory standard,” either by a nib grinder or yours truly. At the end of the day, if you love the look of a pen, and it’s not writing perfectly, consider paying a little extra to make it yours. If you keep it for years, you’ll get more enjoyment from the writing experience than the $20-50 modification fee, and in many cases it’s cheaper than buying a new pen.

Exploring Stock Custom Nibs: The Esterbrook Needlepoint by Kirk Speer

May 11, 2022

In my past few pen show reviews, particularly my review of the Baltimore Pen Show, I remarked on how there are many more nib grinders working at pen shows than there used to be. The result is not only shorter wait times and more options for those looking to tune or customize their fountain pens to their personal preferences, but a wider range of styles and specialties that only make this hobby more fun and more interesting.

A secondary benefit to having more working nib grinders is yet another trend: manufacturers offering pre-ground specialty nibs as an add-on to standard pens. While Franklin-Christoph has done this for years, with their Masuyama, SIG, and Nagahara-ground nibs, Esterbrook now offers a cursive italic (“Journaler”), an architect (“Scribe”), and now a needlepoint, from Kirk Speer of Pen Realm.

Kirk Speer Esterbrook Needlepoint Nib — This Kirk Speer needlepoint nib from Esterbrook balances a narrow line with smooth writing.

Needlepoint grinds, or “extra, extra-fine” or “ultra-extra fine” nibs, aren’t necessarily as popular among enthusiasts as stubs, italics, and architects. They require you to use light writing pressure, or else the sharp tip will dig into the paper, and even with a light hand needlepoint nibs can feel toothy, which some people consider “scratchy.” That said, if you have small handwriting, or need a fountain pen to use for annotations or marginalia, I’m a firm believer that you need at least one needlepoint nib in your collection.

Kirk ground this needlepoint from a fine, as opposed to an extra-fine. Having more tipping to work with on the original nib often leads to better results, in my experience, especially if you value smoothness.

This particular nib, ground for Esterbrook by Kirk Speer of Pen Realm, is smoother than most needlepoints I’ve used, making it a perfect nib for those who want something that writes a narrower line than your typical JoWo steel extra fine nib, but isn’t so fine that it can’t easily be used for everyday writing. I would compare this needlepoint nib to a standard Japanese extra-fine nib (or even some Japanese fine nibs), rather than something like the Platinum Ultra-Extra Fine or the Franklin-Christoph Nagahara nibs. That said, because these nibs are ground by hand, there will lbe at least some variation between them, and the nib I received may not be identical to every nib out there.

Needlepoint Nib Comparison — Comparing the line from a Platinum Ultra-Extra Fine Nib (top), the Franklin-Christoph Nagahara needlepoint (middle), and the Esterbrook by Kirk Speer needlepoint (bottom). The Esterbrook nib writes a wider line, but is much smoother and better for everyday writing than the other two, which many people find too toothy. (I personally love them, but I have situations where I need to write very, very small.)

Takeaways and Where to Buy

Esterbrook has done the pen community a great service by introducing these custom nib options into its standard lineup, and by making it easier to get a custom nib grind as an add-on to your purchase of an Esterbrook pen without having to travel to a pen show or separately send your pen off to a nib grinder for what can be a weeks-long waiting period. While an ultra-fine needlepoint grind may not be for everyone, I found this particular nib to be well-made, and it will have a permanent home among my various Esties.

Esterbrook-Estie-Honeycomb — The Esterbrook featured here is the Honeycomb with Chrome Trim, one of my favorite materials.

You can purchase the nib and pen featured in this review from most Esterbrook retailers, including our friends at Vanness Pens. Typically, the custom-ground Esterbrook nibs cost an additional $48, with most of the markup going to cover the cost of the nib work. (To compare, having a pen ground to a needlepoint typically costs around $50, excluding the cost of shipping.)

Swapping Fountain Pen Nibs: From Easy to Expert

October 13, 2021

One thing that most enthusiasts love about fountain pens is the ability to customize your pen for your writing style and aesthetic preferences. Whether it’s having a custom pen turned from a favorite material, in a shape that’s the perfect size for your hand, or a nib ground to showcase your own style of handwriting, the options are essentially limitless. At the same time, the idea of physically pulling the nib and feed out of your fountain pen and putting it back together again intimidates many people, even seasoned users who have written with fountain pens for years. There’s no reason to be afraid. While changing nibs on your own does merit a degree of caution (just like disassembling a pen for cleaning or filling from an ink bottle), it’s something that most fountain pen users can do without risk of seriously damaging their pen. Today I plan to walk through a few different options, ranging from easily swappable pre-assembled nib units to more complex modifications.

When changing nibs (or doing any sort of pen-related maintenance), I typically like to work on a towel or other soft/grippy surface to keep pens and loose parts from rolling off the table.

Getting Started: Create Your Workspace

Necessary precautions are minimal. Basically, you need a well-lit workspace with a towel or other no-roll surface to hold your pens and nibs. The number-one danger when performing any sort of work or maintenance on fountain pens is dropping a pen onto the floor and cracking the pen barrel and/or bending the nib, so make sure your pens are secure. I typically unroll a towel onto a sink or standing desk and use that as my work surface.

Swapping out interchangeable nib units (discussed further below) doesn’t require any special tools. Otherwise, you will likely need a square of rubber to help grip the nib and feed, and possibly a loupe or other magnifier to align nib tines.

Franklin-Christoph fountain pens use JoWo nibs, so it’s easy to amass a large collection of custom-ground F-C nib units that you can swap between all of your JoWo-compatible pens.

Easy: JoWo, Bock, and TWSBI Interchangeable Nib Units

These days, the majority of pen makers no longer manufacture their own nibs in-house, and instead purchase nibs from third-party companies JoWo, Bock, and to a lesser degree, Schmidt (though I find Schmidt nibs excellent and don’t know why they’re not more widely used). While some people complain about monotony and the lack of expressiveness in how these modern nibs write, there is one key advantage to this uniformity: interchangeability. Many, if not most, pens that accept standard JoWo or Bock nibs use a default nib unit (i.e., a nib and feed seated in a threaded housing) that can easily be unscrewed and used in another compatible pen. Once you start custom-grinding these nib units or gather the range of nib sizes, it becomes a very versatile platform that can allow you to thoroughly enjoy your pen collection.

The process for swapping out a JoWo or Bock compatible nib unit is mostly the same between brands. Gently grasp the nib and feed and turn counter-clockwise to unscrew the unit.

The process itself is simple. First, if the pen you are working on is a cartridge-converter model, remove the converter. Then, gently grasp the nib and feed and turn the nib unit counter-clockwise to remove it. Select your new nib unit, insert it into the section, and rotate clockwise until secure. Do not overtighten, as this can misalign the tines of the nib, at best, and cause stress damage to the nib housing, at worst, in which case you will need a replacement.

Opus 88 pens, which are Japanese-style eyedroppers, add one slight wrinkle to the process. There is a small o-ring attached to the bottom of the nib unit housing. If replacing with a non-Opus nib unit, don’t forget to transfer the o-ring as well. It sits on the plastic “stem” and is easily removable.

TWSBI nib units are slightly different, though still simple. On the TWSBI Diamond 580, you simply unscrew the front section of the pen and slide the nib unit out of the plastic cover (shown here in red but clear on most current 580 models). Insert your new nib unit and reassemble. Because TWSBI sells spare nib units for the express purpose of allowing you to easily switch nibs between pens, you don’t have to worry about voiding your manufacturer’s warranty or otherwise causing unintended damage. I own several spare TWSBI nibs, some of which have been custom ground to specialty nibs such as architects.

Editor’s Note: There has been a lot of press recently about a manufacturing defect that has caused cracks in JoWo nib housings. While I’ve been lucky and have not yet found the issue in any of my personal pens, JoWo has released a series of announcements discussing how they plan to fix the problem. If you have been inspecting your JoWo nib units and discover cracks, please reach out to Meister Nibs, the U.S. JoWo distributor.

Intermediate: Pulling and Setting Friction-Fit Nibs

But what about pens that don’t use interchangeable nib units? Well, the nibs on those pens are, for the most part, equally “swappable” and the process is no more mechanically complex than taking a small square of rubber or other grippy material, grasping the nib and feed, and pulling both out of the front end of the pen’s section using a steady motion. You replace a nib the same way, though you need to be pay attention when reinserting the nib and feed as some pens have grooves or “guides” that determine exactly how the nib is supposed to fit.

The nibs on some pens, especially those with proprietary in-house nibs like this Platinum 3776, do not come in a housing, meaning that the nib and feed sit directly inside the custom section.

So why do I have this categorized as requiring an “intermediate” skill level? Honestly, it’s more about confidence than skill. Sometimes, things don’t go 100% as expected. Old ink residue may cause the nib and feed to get stuck in the section, and you may find yourself having to pull fairly hard or jiggle the nib a bit (gently!) to dislodge it from the pen. Any time you apply force, you run some risk of misaligning the nib tines or cracking the feed. Changing friction-fit nibs properly requires some patience, a willingness to engage in a bit of trial-and-error, and an “intermediate” understanding of how fountain pens work. Finally, keep in mind that if your pen breaks and you can’t fix it on your own, the manufacturer might consider removing or swapping the nib on a pen without an interchangeable nib unit to be a “modification” that voids your warranty. That’s not to say that you won’t be able to find someone who can fix the pen, but you will likely have to pay for it.

Expert: Custom Nib Housings for Maximum Pen Hacking

The last topic I plan to discuss combines the two techniques discussed above in a manner that allows you to create your own custom nib units. Flexible Nib Factory sells custom nib housings designed to pair proprietary nibs and feeds (i.e. Platinum, Pilot, Pelikan, Sailor, etc.) with JoWo and Bock-compatible pens. For example, I pulled a friction-fit medium 14k Platinum nib from a standard Platinum 3776 fountain pen, and inserted both the nib and feed into a JoWo-compatible Flexible Nib Factory housing, which I then seated in an Opus 88 Jazz. The one drawback is that these custom housings won’t accept a converter, so you will need to use a piston filler, eyedropper, or bulkfiller-style (i.e. Conid) pen. Opus 88 pens work great for these types of modifications, though with certain brands like Platinum you may have to trim the plastic end on the back of the feed in order to allow the Japanese-style eyedropper system to close.

A nib unit disassembled. Using Flexible Nib Factory housings, you can pull, for example, a nib and feed from a Platinum 3776 and insert it into the custom housing designed to fit a JoWo or Bock pen. It’s less complex than it looks.

A word of caution: customizing fountain pens in this way is addictive. Since building my FrankenJazz, I’ve also moved another Platinum 14k UEF (Ultra Extra-Fine) nib and a Pilot PO (Posting) nib into JoWo housings, which are now in a Schon Black Ultem and Shawn Newton Shinobi. I’m eyeing several other nibs in my collection that don’t get much use in their current setup…
