A herb grinder has a first cutting element having a first annular body projecting from a base disk having an annular rim, and cutting blades extending from a floor in a first areal region separate from a second areal region having no cutting blades, and a second cutting element having a second annular body with a planar top having a through opening and cutting blades extending from an inside surface of the top, the second cutting element engaging the first cutting element at a specific position wherein the opening through the top lies directly over the second areal region of the floor of the first cutting element having no cutting blades.

A grinder for plant substances includes a first surface and an opposing second surface that is separated from the first surface by a first longitudinal gap so that the first surface and the second surface define a receptacle within which a plant substance may be received. The second surface includes holes through which ground pieces of the plant substance may pass and at least one of the first surface and the second surface includes bumps that extend into, but not across, the receptacle. The bumps encourage rolling friction between the plant substance and the bumps so that the plant substance is ground into pieces small enough to pass through the holes.

A system and method for processing organic material, the system having four stackable housings, each housing defining a compartment, in which a first compartment of a first housing contains upper grinding teeth, and second compartment of a second housing contains lower grinding teeth, and when organic material is added to the second compartment, the upper grinding teeth and the lower grinding teeth work together to crush the organic material into smaller pieces and granules. The second housing contains holes to allow the smaller pieces and granules to fall into a third compartment of a third housing, where a filter catches the smaller pieces but allows the granules to fall to a fourth compartment of a fourth housing. The third housing has Smaller pieces trapped by the filter can be removed a sidewall opening in the third housing, and the granules can be removed through a slot in the fourth housing.

A herb processor has an upper cutting element with blades extending downward, a circumferential groove in an inner diameter of the upper cutting element, and a first opening into the groove from the planar lower end, a lower cutting element with blades extending upward and a laterally-extending key that fits through the opening into the groove, locking the upper and lower cutting elements together.

A container apparatus includes a container body and a container lid. The container body defines a first internal cavity. The container lid is attached to the container body and defines a second internal cavity. The container lid includes protrusions extending within the second internal cavity to grind solid materials.
