The Kaweco Sport was first designed in 1911 as a pocket fountain pen which could be carried everywhere. Based on an octagonal design with an oversized cap, Kaweco Sport fountain pens measure only 10.5cm when closed, but when the cap is mounted on top of the barrel they grow into a 13cm long, standard-sized pen, hence the slogan: "Small in the pocket, large in the hand". The Kaweco Sport range includes fountain pens, rollerball pens, ballpoint pens and mechanical pencils.

The Kaweco STEEL Sport series is made of CNC-machined stainless steel which, unlike brass and copper, doesn't change much with use. It is hand assembled and comes in a nostalgic gift tin. Accessories are available separately.
