To quickly process dried herb flowers into ground material that's easily packed into a vaporizer or used in a recipe, we reach for the Shredder Medium 4-Piece. Compared with lesser models, it grinds smoothly and evenly, producing consistent results. Its uniquely shaped teeth make quick work of the densest flowers, and they stay sharp for years. And its extra-deep collection chamber holds more material than the competition, and it's easy to empty and clean.
