Abstract
The present disclosure describes a grinding apparatus preferably comprised of upper, central and lower bodies that are magnetically connected to one another. The central body is further comprised of cutting edges positioned on a center portion to cut and evacuate herbs. The upper body is comprised of outer grinding teeth that can cut and grind herbs trapped proximate an outer rim of the central body. Inner grinding teeth positioned on the upper body and having curved inner faces abut against a correspondingly cylindrical member of the central body to limit the radial play between the upper and central bodies during operation. A teeth or gear system is also disclosed to provide torque transfer and facilitate the connection between the central and lower bodies.
