Grinder

A device used for grinding weed that breaks cannabis flowers into smaller pieces for joints, blunts, and bowls. Place the nug in between the teeth of the weed grinder, then twist the top and bottom of the grinder in opposite directions to break down the flower. Herb grinders may include a kief catcher in the bottom chamber to gather the kief knocked off from the nug in the grinding process. -weedmaps.com
