Herb grinder
Encyclopedia
A herb grinder is a cylindrical contraption with two halves (top and bottom) that separate and have sharp teeth or pegs aligned in such a way that when both halves are turned, material inside—typically tobacco
or marijuana—is shredded, resulting in a product that burns more evenly.
Herb grinders can be used to make tobacco snuff. Snuff
is produced when tobacco is ground into a fine powder, so it can be consumed without smoking.
Some grinders
also have two or three compartments instead of just one, with a fine screen
separating the bottom compartment from the top. This allows fine particles such as pollen
to pass through, but blocks larger plant material.
Grinders called "four-stages" are also popular. "Four-stages" are similar to regular grinders, but include a second fine screen to further separate pollen
or other tiny plant matter.
Herb grinders are also used to prepare spices and cooking herbs for culinary preparation.
