Workhorse Pens: Pilot S20 Ballpoint

The T.G.S. “Workhorse Pen” series is where I park all of my recommendations for those pens that I personally rely on to get work done. While this series started out as exclusively focused on fountain pens, as my interests have become more eclectic over the years, I’ve expanded the series to cover other categories - namely low-viscosity ballpoint pens.

While the low-viscosity ballpoint pen received its own writeup as a category, I wanted to take a moment to highlight an exceptionally good take on the product: the Pilot S20 ballpoint pen. The S20 has been around for a while, in both ballpoint and mechanical pencil format, though like many of Pilot’s best products, distribution has been largely limited to Japan. Featuring Pilot’s “Acro-ink” (the Acroball refill in a Dr. Grip-style cartridge), the S20 stands out due to its unique shape and feel in addition to the excellent writing experience.

Four different low-viscosity ballpoint pens (well, almost) that I use regularly. From left: Pilot S20, Uni Jetstream 4+1, Anterique Mach Ball in Clear Green, and the Caran d’Ache Infinite 888, which is not technically a low-viscosity ballpoint but has an exceptionally good refill. .

I won’t belabor the benefits of low-viscosity ballpoint ink, because they aren’t necessarily specific to the S20 and I’ve already written about them fairly extensively. To briefly recap, low-viscosity ballpoints are sometimes referred to as “hybrid gel” pens, meaning that they feature smoother ink flow than your typical oil-based ballpoint, while maintaining the faster dry times and increased permanence. The downside? Color selection. I’ve not seen many hybrid ballpoint pens come in colors other than black or blue (and sometimes red and green), as opposed to gel pens, which these days are available in pretty much any color you can think of.

The combination of the gently shaped section and the tactile wood used in the Pilot S20 make for one of the most “usable” pens I’ve experienced. It’s honestly the first pen in a while that just makes me want to pick it up.

Why do I love the Pilot S20 so much? For starters, both the top and bottom halves of the pen feature a concave hourglass shape, which allows it to rest comfortably in my hand. While “feel”, “balance”, and “comfort” are highly subjective, in that they often depend on variables like hand size and writing pressure, I personally consider this one near perfect. The wood barrel gives the pen a tactile feel, making it one of those pens that’s a pleasure to pick up simply because it feels elegant - almost extravagant - despite only costing $25.

The Dr. Grip “Cocoon” refill.

As for Pilot’s “Acro-ink”, to me this refill feels more gel-like than the Uni Jetstream or the Anterique Mach-ball refills, which have a more tactile feel akin to a pencil. Part of this might be that the S20 comes in a .7mm tip size, but I’ve always felt that Pilot Acroball pens lay down a darker, wetter line than their counterparts. This pen is a very smooth writer, so much that I’ve recently started using it for journaling - something I can’t say about other ballpoints in my rotation.

Takeaways and Where to Buy

Since I got my hands on the S20 last year, I’ve not taken it out of my personal rotation. The red and black version sits in my Plotter A5 pen loop, and has become an everyday planner pen for me. The brown and black version lives on my writing desk at home. While the Dr. Grip is marketed as Pilot’s “ergonomic” everyday pen, I tend to find it slightly too large. The S20 better fits my own hand and writing style, while keeping the same excellent refill.

For writing samples, I used standard Target-brand copy paper, since that is how many people have to use their ballpoints at work, school, and otherwise out in the world. Of the three shown here, I think the Pilot Acroball ink is the darkest, followed by the Anterique Mach Ball, and then the Jetstream. All are very good and I use them interchangeably.

As of this week, we have the Pilot S20 ballpoints back in stock in our shop. We sold through our initial shipment around Christmas, but have plenty once again. A few of you have asked about the mechanical pencil version, and the .5mm is on the way as soon as our supplier has it back in stock. (.3mm will depend on interest, so let us know!) The S20 ballpoint is priced at $25 and comes in two colors: Red/Black and Brown/Black. Additional refills are also available. I’ve checked, and these are indeed the same cartridges that fit the Dr. Grip pens sold here in the states, though these are .7mm “Fine” refills whereas most U.S. Dr. Grip pens are sold with the 1.0mm “Medium”. Personally, I prefer the fine, and will likely try to swap one into my Dr. Grip Full Black to see if it gets more use.

Kaweco Sport Piston Filler Redux: Classic Sport vs. AL Sport Piston Comparison

This release took me a bit by surprise. While I did suspect that Kaweco would eventually release a lower-cost version of its initial piston-filling fountain pen, I didn’t expect it to happen so soon. Of course, we’re talking about the just-released Kaweco Classic Sport Piston Filler fountain pen, which arrived Wednesday. Now that I’ve had a few days to mess around with it, I can answer a few of the questions that I received and offer my initial impressions on how it compares both to the standard (cartridge) Classic Sport model and the AL Sport Piston Filler.

View fullsize

The standard Kaweco Classic Sport (top) vs. the Kaweco Classic Sport Piston Filler (bottom).

Kaweco Classic Sport (Cartridge) vs. Classic Sport Piston Filler

• Appearance. As with the AL Sport, Kaweco chose to use the most basic version of the Classic Sport (clipless black with gold trim) as the starting point for the Classic Sport Piston Filler. Capped, you won’t notice any meaningful difference from the standard cartridge Classic Sport other than the gold ring at the blind cap, which you remove to access the piston knob. (The blind cap at the back of the pen prevents the piston from accidentally being turned when the pen is posted.) Uncapped, you will of course see the ink window, tinted grey, which immediately differentiates the barrel on the piston filler from the standard cartridge pen.

• Weight. The first thing about the Classic Sport Piston Filler that struck me was the weight - the pen is notably light, with the added heft from the piston only slightly perceptible in my hand. It’s of course much lighter than the AL Sport Piston Filler, but that’s to be expected given the difference in materials.

• Clip Compatibility. There is no integrated clip in the Classic Sport Piston Filler. The standard add-on Kaweco Sport clip fits, so you can use that as you like. I personally prefer a sleeker clipless look on the Classic Sport, and if I need a clip on a pocket pen, I usually opt for the AL Sport Piston Filler or one of my Art Sport models (which also feature the integrated clip).

View fullsize

Both piston fillers feature ink windows.

Classic Sport Piston Filler vs. AL Sport Piston Filler Fountain Pen

• Overall Aesthetic. The designs of the Classic Sport and Al-Sport piston fillers are distinct, even though the internal mechanics may be identical. Personally, I think the AL Sport Piston Filler looks more upscale, with the curved clip, matte metal body, and greater heft in the hand. Of course, it’s also more expensive, priced at $165 as opposed to $75 for the Classic.

• Clip vs. No Clip. As noted above, the AL Sport Piston Filler features the integrated clip, borrowing the same design from the Kaweco Sport Luxe series and the latest collection of Art Sport fountain pens. The clip is a matter of personal preference that often draws strong opinions. If you absolutely need a clip, you can add one to the Classic Sport.

• Ink Capacity. Both pens appear to use the same piston mechanism, and hold the same volume of ink. While I’ve not done a scientific measurement, the pistons took in enough water/ink to fill approximately 3/4 of the way to the 1ml marker on a sample vial. So I’ll guesstimate approximately .7ml of ink. This is roughly what would fit in a standard fountain pen converter, and probably more ink than you would get in a short international cartridge and certainly more than in the Kaweco Mini Converter. Piston or not, the Kaweco Sport will never be an “ink tank” fountain pen, but the piston pens hold more than enough ink to get most people through a few days of writing.

Takeaways and Where to Buy

This post contains only my initial thoughts on Kaweco’s latest release - one thing I want to see is whether the Classic Sport Piston Filler shares the same excellent ink flow as the AL Sport version. As I pointed out in my post on that pen, having the ink sit directly behind the nib and feed (as it does with most piston fillers) often leads to heavier ink flow and an overall wetter writing experience, which I’ve always found to be a good thing with smaller nibs like those in the Kaweco Sport series. So far, the writing experience has been quite nice and consistent in both the Classic and AL Sport versions, but I plan to do a longer-term test.

Come by our shop and see not just the Kaweco Sport Piston fillers, but also the other new releases like the latest Kaweco Collection AL Sport “Olivine” (shown at left).

We currently have stock of both the Kaweco Classic Sport Piston Filler and the AL Sport Piston filler in the shop. If you’re in the Nashville area, I have two tester pens inked up so you can come by and try them in person if you like. We’ve also just received a major restock of Kaweco Bottled Ink, Kaweco Ink Cartridges, and other styles of fountain pens such as the full-sized Kaweco Perkeo!

During the upcoming holiday season, our store will be open for extended hours. Please check the “About” page for directions and updated operating hours, as well as announcements regarding any special events.

Kickstarter Alert: The Wingback Journeyman Pen

It’s always exciting to see U.K.-based Wingback release a new pen! They’re one of my favorite penmakers working with heavier materials like brass and stainless steel, since they pay close attention to the design and balance, with a focus on building pens that are both durable and capable of being used as an everyday writer. Specifically, Wingback pens and mechanical pencils tend to be shorter in order to offset the increased weight of the metals they use. You might think that this is an obvious point, but you’d be surprised at the number of machined pens on the market that end up too heavy to use for more than a few lines of writing at a time.

Introducing the Wingback “Journeyman”!

While Wingback’s latest release, the “Journeyman”, is a touch longer than the existing “Mechanical Pen”, it maintains an excellent feel in the hand and should be on your list of pens to consider if you’re looking for a durable go-anywhere pocket writer. Even better, this new model has customization options previously unavailable.

View fullsize

The new crown/knock incorporates a milled clip.

For those unfamiliar with the Wingback Mechanical Pen, it features a unique “twist bolt action” mechanism that locks down and, with some practice, can be operated one-handed. The Journeyman uses this same style of knock, but incorporates a milled clip into the crown that allows the pen to be secured to a bag, pen case, or pocket. Personally, I also find that the clip makes the mechanism easier to grip and deploy. Wingback has retained other favorite design elements such as the diamond knurling on the grip (neither too sharp nor too slick - just right!) and a comfortable barrel diameter that once again emphasizes the pen’s usability.

View fullsize

The Wingback Journeyman (right) is only slightly longer than the Mechanical Pen (right). The Journeyman is shown in a combination of brass and stainless steel, while the Mechanical Pen is shown in Black Steel.

So what differentiates the Journeyman from prior Wingback offerings, in addition to the clip?

• Customization. The Journeyman can be customized on a component level, allowing you to mix and match materials. Available in brass, stainless steel, and Black Steel, you can now choose different combinations of metals for the barrel, crown, and clip. The pen I was sent for review features a brass barrel, with a stainless steel crown and clip. A full titanium pen is also available, though you cannot mix and match the titanium components with other materials.

• Refill Compatibility. The Wingback Mechanical Pen used a Fisher Space Pen pressurized refill, which is somewhat polarizing as many people don’t enjoy the way that it feels on the page. (I like it, but it’s not for everyone.) The Journeyman offers more flexibility, as it takes an international G2/Parker-style refill. While it ships with a Schmidt Easyflow 9000, you can choose from any number of ballpoint, gel, or even rollerball options in this format.

View fullsize

The mechanism isn’t complex: simply unscrew the knock and drop in a new refill.

Are there any drawbacks to the Journeyman’s design over the clipless Wingback models? In addition to a bit of added weight from the clip and increased length, I should mention that the edges of the milled clip are somewhat sharp, and can snag your hand if the pen rotates while you’re writing. If you don’t tend to rotate your pen, this may not be an issue, but I’ll also add that my pen is a review sample so the finished product may differ as production specs are finalized.

Takeaways and Where To Buy

As with the other Wingback products I have reviewed, I found the quality to be top notch, and fans of machined mechanical pencils and pens will want to check out the Kickstarter page for full details. With two weeks to go at the time of writing, the Journeyman already has received nearly $100,000 in pledges (blowing past its funding goal of $2000), and Wingback has a track record on Kickstarter, so while Kickstarter projects are never guaranteed, there’s no doubt in my mind that the project will deliver. Current estimates have the Journeyman pens arriving in March 2025. Pledges start at £150 (roughly $195), making it a not-inexpensive purchase, but Wingback has always been known for not skimping on the quality of materials or construction.

Do I Really Hate Rollerballs? Revisiting This Question for the Umpteenth Time

The rollerball and I have shared a fraught relationship over the years. Yes, I’ve tried. I really want to love what many describe as the most “elegant” writing instrument short of a fountain pen. I know they’re supposed to be smoother. I know they’re the “professional” choice. I know the ink is permanent. But for nearly twenty-plus years I haven’t been able to find one that truly works for me. Lately I’ve been trying a bit harder.

What prompted me to revisit rollerballs? I still get weekly questions about them, for one thing, and it’s hard for me to recommend specific items if I’m not familiar with the product category. But beyond that is a general sense that I’m missing something. I regularly have customers who bulk order rollerball refills - there are pen people out there who really love their rollerballs - so I figured I should do a deeper dive.

View fullsize

Five different writing samples, from the top: Caran d’Ache 849 Rollerball Fine in Blue; Montblanc Medium St. Exupery limited edition rollerball refill; Pilot G2 gel refill, for comparison; Schneider Topball 580 fine; and Baron Fig/Schmidt P8127. Note the new “Hex” Baron Fig Squire at the bottom, which Baron Fig was kind enough to send me to test out!

Reasons Why People Love Rollerball Pens

• Dark, Permanent Lines. As I remarked in my recent writeup of the Lamy AL-Star Rollerball, there’s something deeply satisfying about a pen that lays down a dark, bold line, especially when you’re brainstorming on a legal pad or a giant desk blotter. Since the majority of rollerball refills only come in black or dark blue (and less commonly red and green), you’re sure to get a dark line, and the ink is almost always permanent.

• The Smoothness Factor. If you ask rollerball enthusiasts why they love their pen so much, many - if not most - will tell you that it’s because the writing experience is so smooth. Rollerball cartridges contain liquid ink, and most companies use relatively wide tip sizes (.7mm-1.0mm) to guarantee a wet, “smooth” writing experience that seems to glide across the page, especially compared to an oil-based ballpoint.

• Ubiquity and Convenience. Rollerballs are popular, having assumed the mantle of the “executive” pen of choice over the fountain pen during the 1990s. You can typically find rollerball refills in any big-box store, even for higher-end brands like Montblanc, and it’s quite easy to change the cartridge. (Which you may have to do often - see below.)

• Versatility: Both Capped and Capless Options are Available. Over the past 20 years, rollerball technology has improved to the point where there are very good capless refills that allow for a retractable design. Pens such as the Retro 51 Tornado, the Baron Fig Squire, and the Caran d’Ache 849 Rollerball all use capless refills and twist or click mechanisms.

Even on relatively thick Midori MD Paper, you still see the Montblanc and Schmidt refills come through the paper a bit.

Why Rollerball Pens Haven’t Necessarily Worked for Me

• Temperamental Refills. My biggest problem with rollerballs has been that the refills are expensive and don’t last very long. Costing anywhere from $8-10, you would expect to get at least a month or more of writing, yet I regularly come across rollerball refills that dry up and clog long before they actually run dry. I’ve even had refills that don’t write out of the box. If this happens I always contact my retailer/distributor and request a replacement, or I return them to the store.

• Feathering and Bleedthrough. Whether you are writing with a rollerball or a fountain pen, any ink that’s a combination of “wet” and “permanent” will have a tendency to bleed and feather on most papers. Rollerballs can be even worse than fountain pens because the ink is being applied with a sharp tip, which presses the ink into the paper fibers and makes bleedthrough and feathering even more likely. You can, however, find drier rollerball refills to minimize this tendency, and I’ll discuss a few of my preferred options below.

• Lack of Color Options, Namely Blue-Black. Nine times out of 10, I’ll choose a blue-black ink over standard black or standard blue. It turns out that blue-black rollerball refills are hard to come by, and you’ll typically have to seek out third-party “aftermarket” options by companies like Monteverde. That said, I’m more likely to choose a rollerball or fineliner over a fountain pen when I want to write with plain black ink, since it’s typically quite dark.

• I Personally Prefer Fineliners. Most capped rollerball pens are also compatible with fineliner cartridges, and since I genuinely love how fineliners write, I will typically opt for one over a rollerball. Lately I’ve enjoyed refillable fineliners, since I can use my fountain pen inks without worrying about expensive and finicky cartridges. I’m also playing around with a Kakimori “inkball” pen that I was sent as a promotional tester, which also allows you to use fountain pen ink in a rollerball-style tip.

So What’s the Verdict? For Me, a Rollerball Depends Entirely on the Refill

Namely, a drier refill. As much as I may try to “accept it”, I hate feathering and bleedthrough. I think it looks sloppy on paper, and defeats any of the so-called elegance inherent in writing with a nice pen. For this reason, I strongly favor drier rollerball refills that don’t lay a thick line of ink down on the page. My three favorites are:

• Caran d’Ache 849 Parker-Style Rollerball Cartridge. While I have no proof, I suspect that there is gel pen technology incorporated into this refill, because it behaves quite differently from most other rollerball cartridges I’ve tried. The ink does not bleed or feather on most papers, and the versatile Parker-style cartridge fits a wide variety of different pens. There’s even a finer tip available. (Disclaimer: We sell these refills, and quite a lot of them.)

• Schneider Topball 850 Refill. This has long been my “stick” rollerball cartridge of choice for capped pens. It writes a clean, precise line, and fits most European rollerball pens, though you may have to modify the length with tape or a spacer.

• Montblanc Rollerball Refills. Expensive, yes. Short lifespan? You bet. BUT, they’re also well-behaved and feature a relatively wide color selection (including limited editions). Despite being a finicky refill that tends to dry out faster than I would like, Montblanc rollerball cartridges look super nice on the page. Because they are threaded and screw into the pen, there is zero tip wiggle.

I’ve gradually come to accept that a rollerball will never be my everyday carry pen of choice, but I feel like I have a solid stable of refill options I can turn to if I like the design of a specific pen and want to pick one up. It’s also worth remembering that many gel ink cartridges can be hacked to fit rollerball pens, and many smaller manufacturers (like Sunderland Machine Works) are making pens specifically designed to fit both rollerball cartridges and gel refills like the Pilot G2.

What’s your favorite rollerball cartridge? I’m thinking of exploring more Japanese options, such as the Ohto Ceramic series, in the near future, as I’ve heard these tend to favor finer lines and may work better for my style of writing. Stay tuned!
