We should all live in hemp houses. Hemp is an amazing material that is durable, cheap to produce, and has extreme versatility. This grinder from Santa Cruz is made from Hemp Bioplastic which is durable, environmentally friendly and makes perfect sense. The Hemp Plastic Shredder has square-angled blades that will bulldoze through your nugs and break them up perfectly for a blunt, bowl, or joint. If you are looking for a fine grind for vaporizers, you might want to use a metal grinder. But if you are grinding to roll, this one does the trick and is nice to planet Earth.
