Kitchen knives, which need to be quickly sharpened, are preferably honed by our diamond steel D12. This oval steel is covered with fine diamonds and you will find that the result comes fast even if the knife is made of a hard, stainless steel. To insure a long life of the steel, we have covered the surface with titaniumaluminanitrid, an extremely hard and sophisticated material, only is found on exclusive products. The diamond steel is used for establishing the wedge-shape of the edge and in certain cases, the micro-teeth made by the diamond steel might deliver a very good cutting performance, e g for fresh bread.
