Kaweco Brass Sport Fountain Pen Medium Nib Raw Brass

Brass pocket fountain pen

The Kaweco Brass Sport is a fountain pen turned from solid brass with a medium nib. Its compact dimensions make it a practical choice for daily carry in a pocket or small bag. The raw brass finish is untreated, allowing a unique patina to develop through regular handling. This German-made instrument suits writers who appreciate a substantial, metal-bodied pen.

Untreated brass surface changes with use

The raw brass is not lacquered or coated, so the metal reacts naturally to skin oils, moisture and air. Over weeks and months the surface darkens and accumulates fine scratches that record the pen’s history. No two examples age identically, giving each unit an individual appearance. This characteristic is inherent to the material rather than a defect.

Threaded cap and standard cartridge system

The cap screws onto the barrel with a precise thread, securing the nib during transport and preventing it from loosening in a pocket. The pen accepts standard international ink cartridges and can also use a converter for bottled ink. Its short, octagonal profile posts securely when the cap is screwed onto the back. The all-brass construction adds noticeable weight without requiring a large grip section.
