We know how demanding work in a kitchen can be, which is why if you need to sharpen your kitchen knives quickly and effectively, we recommend the D12 diamond steel. This oval-shaped steel is coated with diamond powder, allowing for a fast result even if the knife is made of the hardest stainless steel. To ensure a long life for this steel, Fällkniven has coated the surface with titanium-aluminide-nitride, an extremely hard and sophisticated material found only in exclusive products. The diamond steel is used to restore the shape of the edge, and in some cases, the micro-teeth created by the diamond steel can offer excellent cutting performance, for example, with fresh bread. For a finer final finish, Fällkniven recommends their Ceramic steels.
