Taken directly from the Kaweco Catalogue:
Kaweco is one of the oldest brands in its category. Since 1883 Kaweco writing instruments have been an inherent part of high class assortments. The fine line between tradition and innovation is at the core of this brand. The unmistakable octagonal shape represents individual freedom and maximum precision of design and implementation.
In 1911 something remarkable by the name of Kaweco SPORT was created. A pocket fountain pen which could be carried everywhere. It only measured 10.5 cm when closed, but when the cap was mounted on top of the barrel, it grew to a standard sized pen.
