What Are Metal Herb Grinders?

Materials

• Metal herb grinders are generally made from machined aluminum; however, some brand name models (like Space Case) are made from titanium.

Basic Parts

• By definition, a metal herb grinder will have two opposing faces with interlocking teeth; when rotated, these teeth will chew up the herb, resulting in a ground product.

More Advanced Models

• Herb grinders may have anywhere from two to five pieces; while two are always dedicated to the actual grinding apparatus, the others are designed to collect, or filter, the resulting product.

Storage Compartment

• Some high-end herb grinders have a space below the grinding mechanism. This area collects the material as it falls through the holes.

Filter Screen

• The best metal herb grinders offer a filter screen, which sifts the pollen crystals from the product.
