The original 'Heidelberger Federhalter-Fabrik Koch, Weber & Co.' no longer exists; the trademark rights and production of the modern Kaweco Sport fountain pens lie today with Gutberlet. The historical Kaweco already had compact, cylindrical safety pens for ladies, officers and sport travellers in its programme by 1911, made of guilloché or marbled hard rubber and in special editions of silver, tula or Toledo. Today's Sport models are a homage to this classic design, but the brand's economic significance is no longer comparable with the pre-war period.
