In Fissler Cool Planet, tcc and Fissler have created a range of knives that are in unison with their time. They range aligns the principles of circular design with the desirability, quality and respect that exists within the Fissler brand. Circularity within the range was achieved in three ways: 1) A minimum of 90% recycled stainless steel content; 2) A fully recyclable mono material design; 3) Easily recyclable packaging. These claims have been evidenced by two separate third party audits. Recycled content was verified by UL Laboratories. A life cycle assessment conducted by TÜV Rheinland.
