4 Piece Design
The Sharp Stone Grinder consists of four separate parts that work together. The lid fits onto the grinder with the assistance of neodymium magnets, keeping the lid firmly in place but allowing for the grinding movement. The ground spices can be retrieved in the second section of the grinder. Many holes cut very close together allow the ground material to fall through without getting caught up. The third section allows only the finest particles to fall through the steel mesh, keeping the ground spices separated in the second section. This design requires each unit to be individually machined from a single piece of aluminum, but makes the turning movement as smooth as glass.
