Shop our collection of 2-piece grinders. These grinders are the most basic type of grinder of the bunch, and are the best option for those that want a small, easy to carry grinder. With only two pieces to worry about, these grinders are easy to use. Two halves, loaded with sharp teeth, come together and shred your herbs with a twist and turn. Twist and turn just a few times for a coarse grind, or shred longer for a fine grind.
