A weed grinder breaks down marijuana flowers into tiny bits for joints, blunts, and bowls. To break down the flower, position the nug between the grinder’s teeth and twist the top and bottom of it in opposite directions. In the posterior chamber of herb grinders, a kief catcher collects the kief knocked off from the nug during the grinding process.
Grinders may come as made from different materials such as metal, wood, or plastic. Aside from varied materials, there are also various sizes for grinders, ranging from a two-piece grinder for a casual user to a five-piece one for a veteran smoker.
