“As much as I am not a fan of this pen”— @Volkmannx on YouTube
“I have a kaweco sport classic. But it doesn’t work anymore. Tried everything to get it working again. So I’m scared of getting another one.”— DoraThe214270_mk2 on Reddit
“My Hongdian M2 is awesome! I like it better than my Kaweco Sport. Its metal, too, and has a wonder satiny feel in the hand.”— Supac124 on Reddit
“I prefer the Perkeo over the sport as I don’t really like small pens”— @Neel-y4f on YouTube
“Personally wasn’t a fan of the Kaweco sport. The nib was fine but it just felt so cheaply made.”— Chicken_Man22255 on Reddit
“Stares pointedly at my Kaweco Sport which has dried up in the last couple house because I can't get the barrel unstuck from inside the cap...”— SurLeQuai on Reddit
“Having tried a Kaweco Sport and several LAMY Safaris, I’d recommend going for a Pilot Kakuno or Platinum Preppy. They are cheaper and IMO write better.”— idontknowjackeither on Reddit
“That is until I tried better nibs, I now dislike the Kaweco Sport nibs. Still great pens outside of that.”— Gennnki on Reddit
“I don't even post my kaweco sport! I've never liked the added backweight that the pen gets while writing with the cap posted”— NepGDamn on Reddit
“the pen overall feels premium, much more so than the much more expensive Kaweco Sport aluminum.”— hainguyenac on Reddit
“E.g. I'd argue Kaweco Sport to look no further, is IMO inferior in quality to Jinhao 82, (I'd even say their nibs QA is worse)”— doxasticAgent on Reddit
“While the Kaweco Sport and Fabre Castell Neo Slim wrote beautifully initially I found their build quality to be disappointing which ultimately led to them wearing worse as time went on.”— Acceptable-Pudding15 on Reddit
Not complaints — practical notes from owners that didn't affect the score.
“I post the Kaweco Sport, otherwise the balance feels off while writing since it's such a lightweight pen.”— dapkewitches on Reddit
“Pretty much the only pen I post these days is the Kaweco sport, because it's too tiny without posting.”— doctortonks on Reddit
“the Kaweco sport is not left handed friendly for ME. I truly do have atrocious hand posture”— asian_wreck on Reddit
“The Kaweco Sport is super light (9 grams) and made to be used posted. A converter is available, but it's small; you'll get more ink capacity by refilling cartridges.”— WoosterKram on Reddit
“Every note that's true for the Lamy is true here too except now substantially smaller in size and with facets on the cap (also no convertor, and the convertor you can buy for it is absolutely miniscule).”— TokidokiAi on Reddit
“This got it writing pretty reliably, but not perfect, so I very gently flossed the slit in the tip with a sheet of 800 grit wet/dry automotive paper. PRESTO! It write a perfectly wet, somewhat stubbish line.”— anonymous on Fountain Pen Network
“Never, never, has a Kaweco broken on my travels. And I'm not a hotel traveler. I travel with a mountaineering boot and backpack, and mostly by bike. That's a constant shake. The Kawecos don't mind that at all.”— anonymous on Fountain Pen Network
“Mine was struggling with baby bottom so I followed a video by SBRE Brown and smoothed it out with micro mesh pads since I had a set from before.”— anonymous on Fountain Pen Network
