Your S1X-knife is the strongest, sharpest and safest stainless steel knife in production. If your life is in danger, you can always rely on your S1X. It is designed to withstand all the stresses applied by the human hand, which means that it is virtually indestructible. It assumes, however, that you are careful with the knife and that it is used as intended, namely as a sharp precision tool.
The basis of the X-knife’s strength lies in the laminated cobalt steel, and also in the well-thought-out construction in which break zones have been eliminated. Together with the hand-shaped convex edge, the X-knife is a concept that beats everything else in the world in terms of safety and comfort.
A few words about the all-black version: This surface is called Tungsten Carbide and is among the hardest we have ever encountered. Although we really tried to wear down the black coating with the toughest, driest curly birch we could find, we never succeeded in getting holes in this extremely hard, durable surface. Still, we cannot guarantee that it will stay for time and eternity, after all, the blade can be ground and certainly a diamond or ceramic stone will bite on the surface. Also for example a grain of sand can scratch or leave a mark in the coating. The hardness is at 2400 HV (Vickers) or around HRC 83.
