Abstract
An herb or tobacco grinder is provided in which the cutting surfaces line a series of elongated, curved grooves. The slots or grooves are laterally elongated such as to easily receive leaf material, as well as stem, seed or the like. The slots or grooves are slightly curved in opposite directions and intersect to form an impingement cutting region.
