Pepper and salt mills from William Bounds feature a 3-step adjustment ring that makes selecting your milling setting as easy as 1-2-3; fine, medium or coarse. The milling mechanism works in a way that eliminates metal-on-metal contact, crushing peppercorns and salt crystals rather than grinding them. This means the mechanism will never jam or lock up and allows a lifetime guarantee on the mechanism. Bounds mills operate clockwise or counter-clockwise, making them ambidextrous. s.
