Well, it's here! After years of speculation, and much anticipation, Kaweco has released the piston filler version of the Kaweco Sport. Rather than design a completely new pen, Kaweco adapted the existing AL Sport fountain pen by adding an integrated clip and, of course, the piston filler. What are my initial thoughts? Let's take a closer look.

Initial Impressions of the Design

From the moment you open the box, there's no confusing this pen with anything other than a modern Kaweco Sport fountain pen. As mentioned, the body design draws on the existing AL Sport line, though Kaweco has added the integrated clip from the current Art Sport lineup and the now-discontinued “Luxe” model. There's also a gold band at the blind cap, which you remove to access the piston mechanism.

Kaweco Sport Piston Filler Capped — I’m sold on the integrated clip. It’s a matter of preference, but I was always a fan of the now-discontinued “Sport Luxe” pens that had this same look.

In terms of size, feel, and overall setup, you shouldn't notice much of a difference between the Sport Piston Filler and the existing AL Sport line. My red AL Sport shown below weighs 18g, and my 3/4 full Kaweco Sport Piston Filler weighs 24g. While the piston adds some weight, given the Sport's small size, I don't really notice it.

Kaweco Sport Piston Filler Posted — The pen posts nicely, and the ink window allows you to see how much ink you still have in reserve.

The biggest difference in the body is the vintage-style ink window, which allows you to see the ink level in the pen. The piston filler holds more ink than a cartridge, certainly holds more ink than the small Kaweco Sport “Mini” converter, and while it's not quite at eyedropper level, you don't have to deal with silicone grease, ink burping, and other considerations that pop up when you pour ink directly into the barrel.

Kaweco Sport Piston Filler Piston Mechanism — Remove the blind cap to access the piston knob and refill the pen.

The piston design on this pen is a bit unique. You access the piston by removing the blind cap to reveal the piston knob. Why would Kaweco do this? I suspect it’s because nearly everyone posts the cap on the back of the Kaweco Sport as they write, and this design minimizes the risk of the piston accidentally engaging and expelling ink while writing.

Nib and Writing Experience

The first thing I noticed after inking up my medium piston Sport for the first time was how much the standard Kaweco nib benefitted from the increased ink flow the piston mechanism offered. Piston fillers often deliver a more consistent flow of ink to the nib and feed than cartridge/converter pens, which in turn makes the pen feel like a smoother writer. I find this effect more pronounced with smaller No. 4 and No. 5 nibs. Again, this is strictly a matter of personal preference, but the medium nib in the pen I chose for myself is excellent. (It's also possible that a higher degree of quality control went into the nibs on the $165 pen than goes into the standard $28 Sport. One would hope so.)

Kaweco Sport Piston Filler Nib — The Kaweco Sport Piston Filler uses the same nib as the other Kaweco Sports, but the nib unit is different. My understanding is that Kaweco will start selling replacement nib units specific to this pen.

I won't write much more on the writing experience - I've previously reviewed multiple versions of the Kaweco Sport and the feel of this pen in the hand as you write isn't significantly different. You either like these smaller pens or you don't, and nothing about the filling system really changes that.

"But I Like the Vintage One Better...."

Initial reactions to the Kaweco Sport Piston Filler have been mixed, not necessarily due to the pen itself but rather because nobody knew what to expect, with expectations all over the place. Some, frankly, were wildly unrealistic. (I'm not sure in what world people were expecting an inexpensive piston filling Kaweco fountain pen with a 14k gold nib, or an exact replica of vintage pens featuring materials that can’t be sourced.)

Keep in mind that the modern company we know as "Kaweco" is different from the legacy company that produced vintage “Sport” fountain pens. Much like "the new Esterbrook", the rights to the Kaweco name were acquired by a new manufacturer who began making modern pens inspired by the heritage designs.

I believe this context is important to understand because creating a piston filling Kaweco Sport is not as simple as "turning on the old machines". As with most vintage pens, the machines and tooling used to make the pens likely don't exist anymore - much less in workable condition - and the gold nibs and other materials used in the vintage manufacturing are either much more expensive or entirely unavailable to modern manufacturers. A piston-filling Kaweco Sport in a vintage-style body different from Kaweco's current lineup, featuring a 14k gold nib, would easily top $200, and I would probably pitch it closer to $300+.

On the "Value Proposition" and Appreciating Trade-Offs

Now for some “market discussion”: There has been a lot of talk about the price point of the Kaweco Sport Piston Filler ($165), which many believe is too high. While the pen is certainly not inexpensive, I don’t see how a German-manufactured piston fountain pen from a mainline brand could cost less than $130 given the realities of the market. (At some point in the future, we might see some minor price drop on this pen as we did with the Art Sport, thus I’m calling $130 as the ultimate floor here even thought the price currently sits at $165 for the pen / $175 for the pen+ink set. A cheaper pen would almost certainly be a resin model.)

Kaweco Sports Piston vs. AL Sport — Will we see more colors of the Kaweco Sport Piston? Probably eventually, but not right away.

Does it represent "good value"? Frankly, I’m not sure how a piston-filling pocket fountain pen, styled in very specific manner, can even be viewed from a “value” perspective. I see this as a niche product that will likely appeal to a smaller number of people than something like a TWSBI demonstrator. The price reflects that. If what you're looking for is a durable pocket fountain pen with a decent nib that easy to refill and costs as little as $28, that already exists in the form of the standard Kaweco Sport. You can also purchase the AL Sport for $90, which is virtually identical to the piston filler (albeit with different trim and minus the integrated clip). Honestly, the price point here surprised me in a very different way from most people, as I was expecting $200+, especially after the $300+ Ebonite Sport release.

And, yes, if you really want a gold nib, and you prefer the vintage styling, those are very much available on the secondary market (an entirely different set of considerations unique to vintage pens and their maintenance).

Takeaways and Where to Buy

I'm enjoying the new Kaweco Sport. Like most Kaweco releases, the build quality feels high, and Kaweco has done a nice job translating the piston filling system to the existing AL Sport format. Because smaller nibs can sometimes be stingy with ink flow, the piston mechanism seems to vastly improves the writing experience for those who enjoy a wetter nib, and for this reason alone the Sport Piston Filler will likely become my default Kaweco for when I want to do a lot of actual writing, as opposed to quicker notetaking on the go.

Kaweco Sport Fountain Pens with Integrated Clips

You can purchase the new Kaweco Sport Piston Filler at most Kaweco retailers, including directly from us via the T.G.S. Curated Shop. We currently stock the pen in a gift set that ships in a commemorative tin with a bottle of Kaweco Royal Blue ink for $175. The pen on its own sells for $165, and after this initial shipment Kaweco will begin stocking retailers with stand-alone pens. It will be interesting to see whether this takes off, with more colors available, or whether it remains a one-off in the overall lineup!

The Gentleman Stationer is supported entirely by purchases from the T.G.S. Curated Shop and pledges via the T.G.S. Patreon Program. We greatly appreciate your direct support!

I've dabbled in vintage pens over the years, but always as a user, and never really as a collector. It's not that I dislike vintage - on the contrary, I love old things, especially practical items that have survived a century or more of heavy use and remain in nearly as good of shape as they were the day they were made. It's more that by the time I arrived in this hobby, I was struck by a feeling that I was too late to comfortably “collect” within my means. Antique store dealers, flea market vendors, and eBay Sellers had all gotten wind of the resurgent interest in fountain pens and prices seemingly went through the roof, even on pens in so-so condition that needed restoration. While I'm always game to start from scratch and learn about a new hobby, including restoring old pens myself, I didn't have much interest in perfecting my skills at $50-150 a pop. While I’ve learned to do basic repairs like changing sacs and Vacumatic diaphragms, that's the limit of my competence, and I would never feel confident enough to work on pen of any significant value.

So, my experience in vintage largely has been limited to purchasing already restored, nicer pieces that are ready for writing, as opposed to the more "completist" approach to collecting that you might see at pen shows. While I mostly own modern pens, I have a few vintage examples, including a couple of Parker Vacumatics, Pilot Myus, some late-model (1980s-1990s) Watermans and Sheaffers, and now my most recent addition, a vintage Kaweco Sport.

As you can see from the inscription, this is a Kaweco Sport model “V16,” with a “Fine” nib. The facets on this version are more subtle, more akin to the Art Sport than the standard model.

Kaweco Sport: Vintage vs. Modern

Before we dive into a comparison of the vintage Kaweco Sport and the modern pen that you can still purchase today under that name, some brief background on the company itself may be helpful. The original Kaweco (a contraction of Koch, Weber & Co) operated from the late 1800s until the early 1970s, and manufactured several models of pens in addition to the Sport, including the Special, the Elite, and the Dia, all of which you may recognize since the modern company, resurrected in 1994, has released pens under those names. Kaweco actually made multiple versions of the Sport over the years, and the version I own is the last version made in the early 1970s before the original company went out of business. It's part of a commemorative fountain pen and ballpoint set made for the 1972 Munich Olympics, complete with a leather case and medallion.

The modern Kaweco Sport is generally a larger pen than the vintage model that I own. It's longer and more substantial, and from what I can tell based on studying the pictures in Andy Lambrou's Fountain Pens of the World, was based on a 1930s version of the Sport with more pronounced facets on the cap. The vintage Sport feels quite small in comparison, though when extended and posted for writing it's actually a touch longer than the modern Sport.

What else is different? While the modern Kaweco Sport has developed a well-deserved reputation as an inexpensive pocket pen with a steel nib perfect for both beginning fountain pen enthusiasts and experienced users, the vintage Sport featured a 14k gold nib and a piston filling system. The weight of the vintage pen shocked me a bit - despite the integrated piston, it's only slightly heavier than the modern pen. I really wish Kaweco would reissue this classic design, even though the cost of the piston (and the gold nib, if they decided to go that route) would likely require a significant price increase, which I suspect is the main reason it hasn't happened yet.

The nib on this vintage Kaweco Sport writes well, and leaves a moderately wet line, though I’d call it more of a fine-medium than a true fine. Check out that ink window!

I love how Kaweco retained the same script on its modern Sport series. The ballpoint has aged better than the fountain pen, probably due to the fountain pen seeing heavier use.

The finial/medallion on top of the pen is another vintage design element that Kaweco retained on the modern Sport.

Final Thoughts and Where to Buy

I love this little pen. Despite being nearly 50 years old, it feels as sturdy and well-made as a modern Kaweco, though I likely won't tempt fate by using it for true pocket carry. And while I have no plans to dive back into vintage pen collecting, it's tempting to pick up a few more examples of vintage Kawecos, especially if the pens remain as functional as this one. The Munich Olympics connection also makes for a cool piece of history to own.

I purchased this vintage Kaweco pen set from Maria, who sells through her Etsy store MaryMagicBox, which I discovered thanks to a tip from a member of our local Nashville-area pen group. Maria stocks a wide range of restored vintage pens, along with some gently used modern pens, with a focus on German brands such as Montblanc, Pelikan, and Kaweco, along with other lesser known marks including Osmia (later acquired by Faber-Castell). Though vintage Kaweco Sports are less common, they do come up from time to time in Maria’s shop, and she has other models of Kaweco pens available for purchase. If I do get the itch to acquire more vintage, I wouldn’t hesitate to order from Maria again.
