As its name suggests, a grinder is a tool used to speed up and simplify the process of grinding hemp into a fine consistency that most consumers prefer.

The most basic style of these palm-sized cylindrical-shaped tools consist of two interlocking halves, top and bottom, that when separated reveal metal teeth patterns designed to shred and tear dried cannabis into a consistent grind.

Dry cannabis flower is placed in between the teeth of the grinder, and then the top and bottom halves are locked together and twisted in opposite directions. This twisting motion moves the teeth together, catching the dry flower between them and breaking it down into small, even particles.

Herb grinders, sometimes referred to as a “bud grinders,” also come in 3-Piece and 4-Piece designs, with additional chambers and screens that make it easier to remove your dry herb after it’s been ground. Grinders are usually made of wood, metal, or plastic, and come in a variety of color options.
