A herb grinder is a mechanism with two halves that separate and have sharp teeth or pegs aligned in such a way that when both halves are turned, material placed inside is effectively shredded. Herb grinders are available in various sizes, colors, materials and price ranges. Herb grinders take your herbal blend and grind it to pieces that are suitable for use with vaporizers and is also used as a kitchen tool to prepare spices and cooking herbal blends. The herbal blends are usually dried, and can consist of flowers, leaves, roots or barks. Some grinders also have two, three or four compartments instead of just one, with a fine screen separating the bottom compartment from the top. Get your favorite herb grinder now!
