My first impression was that your poor ink flow was due to machining oils, I would have started by that first. Other than that, I agree that it is a substantial yet comfortable pen and it has a great design (IMHO much better than its clones). Mine has aged nicely, and I suspect it will still evolve its patina. That's another plus for me, the organic surface and that it is raw, not varnished as the clones gives -again IMHO- a distinctive feeling. I hope you like the patina yours may develop, but if you don't, you can always polish it. Limited edition Kaweco Bronze Sport Pens and Pencils will darken and develop unique patinas over time. Available as ballpoint pens, fountain pens, gel pens, and mechanical pencils, these writing instruments are weighty yet well-balanced, perfect for those who prefer more substantial tools. When writing with the pen I found its weight to be no problem at all. As I probably have average size male hands, I have to post the pen for anything exceeding just scribbling down a phone number or so. A substantial amount of the weight is in the cap so that the weight of then pen, when writing posted, rests against the hand and does not have to be moved around with the nib movements.

The Kaweco Ebonit Sport Fountain Pen is made from real ebonite. This natural rubber material was used to make fountain pens during the early 20th century. The Brass line becomes even better with age. The solid brass pens take on a unique, vintage character as they patina with time and handling. These weighty pens are even more substantial than aluminum Sports, but they are just as well balanced in the hand. These crisp italic nibs are available in four sizes. You can use them for bold writing or edged calligraphy. Kaweco’s Brass Sport ballpoint pen is immediately recognizable with its characteristic octagonal shape, which was first introduced in 1935. It has the kind of charm that never goes out of style. The chunky yet elegant design is also practical, as the octagonal cross-section lets the pen sit flat on a table without rolling away. I very much like the look and feel of the brass and I also like the fact that the pen has a design that has been around for so long and probably can be called timeless.How to tell if a pen is wet or dry.

It would be unfortunate to see a beautiful pen damaged or dissolved by cleaning with the wrong supplies (especially since you mentioned that your friend was a "clean-freak". The 'raw' brass finish has no lacquer to wear off. Instead, the bare metal, like the pen's owner, will reflect the trials, tribulations and joys of a lifetime's work and play, with with the surface mellowing over time to a fine burnished patina unique to it's history. The Kaweco Ebonit Sport is made from ebonite, one of the most popular materials for making fountain pens in the pre-plastic days of the early 20th century. Ebonite is a type of natural rubber, and it has a warm, luxurious feel in the hand unlike any other material. Sorry! I meant the Chinese pen maker's lacquer pen with the butterflies and inlays from the previous link. The mechanical pencil shares its retractable design with the ballpoint pen. All the mechanical pencils are refillable with 0.7 mm lead.
