Device and method for grinding herbs and tobacco

A handheld grinder, comprising:

• a housing having a cylindrical body portion, a top end, and a funnel portion opposite the top end and connected to the cylindrical body portion, wherein the funnel portion tapers inwardly from the body portion to a lower end with a bottom opening, wherein the housing has an interior space between the top end and the bottom opening that is configured to receive a material;
• a rotor having a shaft extending into the interior space of the housing and having a plurality of rotor blades extending from the shaft, wherein the shaft is configured to rotate relative to the housing, and wherein a longitudinal axis of the shaft of the rotor is aligned with a longitudinal axis of the housing, wherein the handheld grinder is sized to fit into a user's pocket;
• and
• an auger having a shaft operably engaged with the shaft of the rotor, the auger having at least one blade twisting about the shaft of the auger, wherein the rotor is configured to rotate relative to the housing such that the plurality of rotor blades grind the material into smaller pieces, wherein the auger is configured to rotate independently of the rotor such that the at least one blade of the auger transfers smaller pieces of the material out of the bottom opening.
