Kaweco Brass Sport Fountain Pen
The Kaweco Brass Sport is a pocket-sized fountain pen that when posted transforms into a full-sized pen that easily fits in your hand. The brass will pick up its own unique patina and pattern of scuffs and scratches over time as you use and transport the pen, making this version of the Sport truly unique to you. It comes with a stainless steel nib and an ink cartridge to get you started writing right away!
It accepts short standard international cartridges. Kaweco converter and optional clip sold separately.
Note: This pen comes with an ink cartridge stored in the body. If it doesn’t fall right out, you can get it loose by giving the body a few solid taps on a hard surface.

Customer Reviews
I’m very happy with this pen. It feels good to write with it. I like the heavier weight. Also like the size being smaller when the lid is on,
I purchased the brass version of the Sport in large part to see it develop patina. And boy did it, just a few days in my pocket and it’s developed a lovely patina. Good thing my stint of owning Harley’s and polishing chrome gave me an adversely to polishing and a love of all things patina. I wonder if I could call my aging skin patina?? Hummm. Anywho this is a quality pen, built like a tank and should serve me for the rest of my life and then some.
Packaging was overdone and appreciated. Shipping was fast.Regarding the pen itself, I think it is a different experience from a plastic body Sport, so you really can't get too much indication of how you would like this brass Sport simply by using a plastic body version, imho. I do not find too much of a brassy smell, as some people mention. In fact, I would prefer if there were more.Machining of the body and cap is very well done. The weight is actually ideal for me. It feels really nice to hold and carry. When it is posted, it is near perfectly balanced; unposted works for quick notes too. I think in 'person', it has a cooler minimalist/industrial look than photos may deliver otherwise. I really like a smaller nib size, since it helps maintain a more low key look, despite the shiny brass. Though eventually some patina will curb the shine, and that will also become a personalization of the pen, which is a very nice side-effect if you choose not to clean it. It may be a perfect travel/pocket/edc pen. Great for notes at job sites, or for random thoughts during the day. I can see it as a good pen for students, I would likely have used it if I were in the hobby when I was back in school. In general, as a minimalist, I rate this Brass Sport second to my favorite of all fountain pens, the Lamy 2000. The Brass Sport serves a different use case and I feel more comfortable leaving the house with it in my pocket, due to it's size and construction.
Very nice, sturdy, well constructed pen.
Thoughts from a long time Goulet customer on the Kaweco Brass Sport Fountain Pen. I have owned this for a couple years now as my go-to notebook pen. It's got a great patina and I often get compliments on it. Here are other things to consider:- It wouldn't stay posted. Following the advice of several others on the blogs, I put a little square of scotch tape near the top of the pen barrel to give the cap something to cling to. Stays on now, but really Hans?- I finally sprung for the solid gold nib. I lived with the steel nib and then tried the gold-plated one, but the EF in anything other than gold was stiff and scratchy. Gold one writes like buttah.- I got the gold clip, since it matched the nib and made the pen easier to handle and not roll around. Like adding a clip to a pocket knife. Clip should come with this pen, but I guess people like to pick their own color.- I bought a short leather pen sleeve from Popov Leathers. It protects my pocket (it never has leaked) and I can tuck in a spare ink cartridge, which is good because the pen only holds tiny ones. BUT there must be plenty of room up there. I had to stuff a foam ear plug up into the barrel because 2 or 3 times the cartridge popped off and the nib started to unscrew and ink leaked in the cap. Not good. Doesn't go anywhere now with the earplug holding the cartridge in.Does that seem like alotta tinkering for a $100 German-engineered pen that I spent $250 on?Yes, but it is mine, and I will keep it always.
FAQs about Fountain Pens
How do I fill a fountain pen with ink?
It depends on the pen's filling mechanism, which you can find in the Technical Specs section above.
Here's a quick definition of the most common filling mechanisms:
- Cartridge - A small, disposable, sealed plastic reservoir that holds fountain pen ink. These come pre-filled with ink, and typically you just push to insert them into place and you'll be ready to write! Check out our quick guide here.
- Converter - A detachable and refillable ink reservoir that allows you to use bottled ink in a cartridge-accepting pen. Typically you will install the converter into the grip section, dip the nib/feed into the ink, and twist or pull the converter knob to draw ink into the converter. Here's a video for how to fill a cartridge/converter pen using a LAMY pen as an example.
- Eyedropper - A pen that utilizes the entire barrel as a reservoir for ink. Ink is directly filled into the barrel, allowing for a high ink capacity. Here's a video on how to do it!
- Piston - A type of filling system that uses a retracting plunger inside a sealed tube to draw ink into a pen. They are typically either twist or push-operated. These pens cannot accept cartridges or a converter, and only fill from bottled ink.
- Vacuum - A push-style piston that uses pressure to fill the large pen body with ink. They seal the ink chamber when closed, making it ideal for flying without risk of leaking. Check out our video on how to use a vac filler here.
Check out more info on these filling mechanisms including a video on how to fill each one on our blog.
How do I clean a fountain pen?
It depends on the filling mechanism, but it mostly comes down to flushing it out with water, and sometimes a little bit of Pen Flush if the ink is really stuck.
It's a bit easier to show than to tell, so we've put together a few quick videos showing you the process:
How often do I need to clean my fountain pen?
We recommend a good cleaning every 2 weeks, and any time you change ink colors.
Water will usually do the trick, but we recommend you use our Goulet Pen Flush if the ink has been left in the pen for a while and could have dried up, or when you’re switching ink colors.
My pen won’t write! What do I do?
First things first... make sure you have ink in the pen! Be sure that the ink cartridge or converter is seated properly in the pen, and that you aren't out of ink.
We always recommend you give your pen a good cleaning first, using our Goulet Pen Flush, or a drop of dish soap in some water. New pens often have some machining oil residue left in the feed, so a good cleaning often does the trick first.
If that still doesn't work, try priming the feed. This consists of either dipping your pen nib and feed in ink, or forcing ink from the converter down into the feed.
If it’s still not working after that, please reach out to us so we can help!
