The Door Knocker series features unique and pure design details. The series is influenced by travels through some of Europe's greatest cities and their rich history.The doors in these cities have distinct elaborate door knockers that fuse function and design and are in their own way, beautiful works of art.

The London Door-Knocker Ring with its bold but subtle spikes references the British city's punk past - from Vivienne Westwood to Johnny Rotten. It features a moving door-knocker ring on top, and five square shaped spikes equally spaced around the band of the ring. The spikes are consciously placed around the band of the ring, making it comfortable to wear, and perfectly fitting between the fingers. Inscribed with the Linn Lømo monogram for authenticity.
