Human Grade Grinder 1A – 4 Piece – 2″

Human Grade uses an alphanumeric naming system across their grinder range. The number indicates the size tier — 1 is the smallest compact 2-inch size, 2 indicates the 2.5-inch size, and 3 indicates another compact 2-inch variant with a distinct design. The letter indicates the specific design variant within that size tier. The 1A is the classic straightforward 2-inch model with a smooth exterior and standard design. Other Human Grade models at the 2-inch size include the 3A, which features a concave design with ergonomic notches. All Human Grade grinders use aluminum construction and include a magnetic lid, pollen screen, and scraping tool.

Yes. At 2 inches in diameter, the Human Grade 1A is one of the most pocketable 4-piece aluminum grinders with a kief catcher available. It fits into a coin pocket, small pouch, or jacket breast pocket without creating any meaningful bulk. The magnetic lid closure prevents the grinder from opening accidentally during pocket carry. The 2-inch size does mean the grinding chamber holds less per load than larger grinders, so users who grind multiple times per day may need to reload more frequently. For solo users who grind primarily for a single session at a time, the 1A is a practical everyday carry choice.

Yes. The 4-piece design includes an integrated pollen screen and a kief collection chamber at the base. Ground herb falls through the grinding plate holes into the storage compartment, and fine trichome particles pass through the pollen screen into the bottom kief chamber over multiple sessions. The included scraping tool is used to collect accumulated kief from the chamber walls and floor when enough has built up to harvest. The 2-inch chamber accumulates kief more slowly than larger models due to the smaller total herb load per session, but it still provides meaningful pollen collection over time with regular use.

The Human Grade 1A delivers the core 4-piece grinder features — magnetic lid, sharp teeth, pollen screen, kief catcher, and scraping tool — at an accessible price without the premium materials or specialized manufacturing of higher-end models. It does not use aircraft-grade aluminum alloys like 6061, medical-grade ultrasonic cleansing like the Santa Cruz Shredder, or specialty tooth geometries like the Stache Grynder. For users who want reliable grinding with kief collection at a lower cost, the 1A performs well within those parameters. Users who grind daily for extended periods and prioritize longevity, grind quality, or kief quantity may find more value in a higher-investment grinder over time.

The Human Grade Grinder 1A is available in multiple color options. Confirmed colors include black, purple, red, blue, green, and silver, though specific availability at Haze Smoke Shop depends on current inventory. The classic design and smooth exterior suit any color choice equally, as the grinder has no textured or design elements that interact with the color selection. All color options perform identically.

After each session, use a small brush to clear herb from the teeth and storage chamber. Disassemble the four pieces and use the scraping tool to collect kief from the bottom chamber before cleaning. Soak all aluminum pieces in isopropyl alcohol for 15 to 20 minutes to dissolve resin buildup. Brush away loosened residue, rinse with warm water, and allow all pieces to dry completely before reassembling. The pollen screen should be cleaned by soaking rather than pressing directly on the mesh to avoid distorting it. The magnetic lid area can be wiped with a damp cloth to remove herb particles from the magnet face.
