I originally come from the "City of Blades", I have good contacts with professionals ... and again good contacts with the materials testing institute; I have there times sent there a knife, with the result: scrap. The knife withstands any test. One can already see from the blue staining, ie the blade may have been cured, but is sw in the final editing was "blue ground", a clear error in the processing. In a good Solinger grinding to throw something on the scrap !!!!! in Switzerland and / or BOSCH apparently not.
