We are proud to announce that we have been part of an extraordinary pilot project. Together with several companies from Solingen, Wuppertal and Remscheid, we have designed and produced a knife that consists of 100% industrial waste. The name "Zirkelmesser" refers to the cycle of recyclable materials during production. In this process, the task of sharpening fell to us, for which we are naturally more than predestined.

The innovative pilot project initially comprised 200 copies, for which orders have already been placed. Depending on the success of the project, production is to be expanded. Special attention should also be paid to the eco-balance of the "compass knife". Compared to standard production, only about one seventh of the energy and one hundredth of the water is needed in its manufacture. The CO2 footprint also shrinks to one sixth. For the consumer, however, the exceptional production method is not reflected in the price. This is around 40ÔéČ.

The "Zirkelmesser" project was initiated by "RegRess" (Regional Resource Management), which in turn is one of seven individual projects under the umbrella of the project "Urban Production in the Bergisches St├Ądtedreieck - Competitiveness, Innovation and Neighbourhood Development". The aim of "RegRess" is to recycle waste materials from the metal processing industry and to manufacture new products from them, in this case a knife.

We would like to thank everyone involved for the great cooperation and hope that we can continue this in the future.
