GRAV 3 Piece Grinder

The GRAV 3-Piece Grinder addresses clogging through two design choices. First, the 15 teeth are spaced farther apart than is common in budget grinders, which means there is adequate clearance between each tooth for herb to pass through freely rather than packing between tightly spaced teeth. Second, the holes in the base of the grinding chamber through which ground herb falls into the storage compartment are also generously sized and positioned to allow consistent flow-through without compaction at the openings. The elongated curved blade geometry of each tooth also ensures the chamber is fully covered without dead zones where herb could stall and accumulate.

The GRAV-branded aluminum scraping tool is included specifically because the storage chamber of the GRAV 3-Piece Grinder has a curved interior that matches the curvature of the scraper edge. This means the scraper can sweep the full interior arc of the chamber in a single motion, collecting all ground herb from the walls without leaving residue in the curve. Most grinders include a flat scraper that does not match the chamber curvature, requiring multiple passes and leaving material behind. The GRAV scraper is a small detail that meaningfully improves how thoroughly users can collect every bit of ground herb from the chamber, reducing waste.

Yes. The GRAV grinder produces a medium-fine, fluffy grind that works well with most dry herb vaporizers. The elongated blade tooth design shreds herb into a consistent particle size without compacting it into a fine powder, which is the output preferred by both convection and conduction vaporizers for efficient extraction. For convection vaporizers specifically, which rely on airflow through the herb bed, the non-compacted fluffy grind from the GRAV maintains adequate airflow through the chamber. Users who want a finer grind for vaporizers can perform additional grinding rotations, and the 15-tooth spacing allows extended grinding without clogging.

Yes. The GRAV 3-Piece Grinder is available in multiple anodized aluminum color options. GRAV typically offers the grinder in colors including black, silver, rose gold, sea green, midnight blue, and similar options, though specific availability may vary at Haze Smoke Shop. The anodized finish integrates the color into the aluminum surface for durability rather than applying it as an external layer. Each grinder also ships with a small GRAV carrying bag. The GRAV logo is incorporated into the design of the grinder body. Color selection does not affect grinding performance.

The GRAV 3-Piece Grinder is exceptionally compact for a full-featured 3-piece aluminum grinder. At 2.25 inches in diameter and only 1.25 inches tall, it is one of the thinnest grinders in the personal-use category. The slim profile allows it to sit flat in a pants pocket without creating visible bulk. The strong magnetic closure ensures the two halves do not separate during pocket carry, keeping ground herb contained. The included GRAV carrying bag adds additional organization and protection for users who carry the grinder in a bag or pouch alongside other accessories.

For routine cleaning, use a small brush to clear herb particles from the 15 teeth and the drop-down holes after each session. The GRAV aluminum scraper can be used to gather any remaining herb from the storage chamber. For a thorough deep clean, separate the three pieces and soak them in isopropyl alcohol for 20 to 30 minutes. Brush away dissolved residue, rinse thoroughly with warm water, and allow all components to dry completely before reassembling. The anodized aluminum surface is alcohol-resistant and will not be damaged by this process. Because the GRAV is a 3-piece grinder without a screen, cleaning is simpler than a 4-piece setup and requires only the two chamber pieces and the lid.
