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.
