This innovative grinding mechanism enables easy, one handed operation. Simply shake the grinder up and down for perfectly ground salt and pepper. The secret to this new mechanism is the helix shaped teeth at its core. Meticulously engineered, they guide and hold the peppercorns or salt crystals to enable a perfect grind every time. They are the subject of both an innovation and utility model patent. A benefit of this new grinding mechanism is that it has allowed the designers to reconsider the shape and texture of the product.
