Experts agree that the German-made grinding mechanism is the best available. In contrast to other grinding mechanisms, the teeth are like those of a hand-finished file. They are individually formed by a technique producing unbeatable sharpness and precision. The grinder itself is made of solid carbon steel, hardened and surface treated to prevent rusting. The remaining metallic parts of the mill are made of stainless steel. The grinding cone and ring are designed so that both large and small peppercorns are cut rather than crushed. The teeth do not become easily clogged. The grinding mechanism of the salt mill is made of high quality ceramic materials.
