A portable manual grinder has a driving section, a grinding section and a discharging section coaxially connected from top to bottom. The driving section has a drive shaft that drives a central axis of the grinding section. The drive shaft is connected to a gear set that increases the gear ratio to facilitate manual grinding. The grinding section comprises an upper grinding section and a lower grinding section that are coaxially disposed and mated together. The upper and lower grinding portions include corresponding blades extending therefrom. The bottom section of the lower grinding section has one or more holes in communication with the discharge section. The driving section and the upper grinding section are magnetically attracted and connected to each other and the upper grinding section and the lower grinding section are magnetically attracted and connected to each other.

A vegetable matter grinding assembly for grinding vegetable matter for smoking includes a first cylinder that may contain vegetable matter. A grinding unit is removably coupled to the first cylinder and the grinding unit is selectively manipulated. The grinding unit includes a plurality of blades to grind the vegetable matter into a plurality of fine particles. The fine particles are selectively smoked and inhaled from a smoking device.

An herb and spice grinder has a plurality of sections that are removably connected together. A hole is formed at the outer periphery of each of the plurality of sections. The plurality of sections can be rotated relative to one another so that the holes align to form a passageway. The bolt of a lock can be inserted through the passageway so as to prevent the sections from rotating relative to one another and to prevent the sections from being separated from one another. As a result, undesired access to the contents of such herb and spice grinder is effectively prevented. Preferably, rotation of a top section relative to an intermediate section causes a grinding of the herb or spice. The ground material passes through openings in the intermediate section to be stored in a receptacle formed in a bottom section. A blade for a grinder is also disclosed.

A portable grinder for herb or vegetative material comprises a top section having a motor and disc with a plurality of top grinding knives protruding downward, a middle section having a plurality of bottom grinding knives protruding upward and a plurality of apertures, and a bottom section. In one embodiment, ground material is discharged through apertures in the middle section, where the size is regulated by a screen, and/or is retained in the middle section until the top section is removed. In a further embodiment, the grinder may be operated electrically or manually.

A container stores, grinds, and measure material. The container includes upper and lower grinding sections that are mated together and rotated to grind the material. A collection section is below the lower grinding section and includes a mesh screen to filter particulate. The mesh screen also functions as a scale to weigh the contents in the collection section. An electronic housing includes a display, microcontroller, one or more buttons, a communications device, and a power supply. Below the electronics housing is a container section retained by a container holder that also includes a scale. The container is enabled to communicate with an external computing device through an application to send and receive data and commands.
