The classic O.G. Cali Crusher® has been the affordable favorite since 2010 and continues to grow in popularity. Unlike other imported grinders, their CNC Machined Grinders are one solid piece of aerospace aluminum. The blade plate will never loosen and spin in place. This design uses diamond cut teeth to crush your herbs into a blended fluffy consistency. It keeps your fingers clean and your bowls evenly packed. Hands down, the O.G. is the best grinder you'll find at this price point.
