The Kaweco Sterling Sport fountain pen is the brand's most luxurious fountain pen ever made, weighing 56 grams of pure 925 sterling silver and featuring a rhodium-plated 14 karat gold nib. The gold nib gets coated with a shiny white-silver dip through the rhodium plating, making the nib more durable.

The components of the barrel are CNC milled from a block of silver with fantastic precision. During the production process, approximately 50 grams of pure silver shavings per fountain pen are sent back to the refinery to be painstakingly recycled and reused for other writing instruments. Each part of the fountain pen is produced in Germany and also manually assembled. The fountain pen gets its excellent finish from careful polishing by hand.

The writing instrument is processed without surface protection, which means that it develops signs of use and the "handwriting of its user" right from the first use.
