The Human Grade Grinder 1B is a 2.5-inch manual device engineered for the efficient processing of dry botanical materials. Built from lightweight aluminum, this 4-piece grinder provides a durable yet portable solution for users preparing materials on the go. Its 63mm diameter offers ample surface area for a comfortable grip during rotation, while remaining compact enough to fit into standard day bags. Designed with a standardized, multi-chamber layout, it ensures that materials are broken down methodically. Available in assorted color options ranging from Gunmetal to Light Blue, it balances functional construction with aesthetic variety.
Diamond-Cut Grinding Teeth
The upper and lower sections of the grinder are equipped with sharp cutting teeth configured in a diamond-cut shape. This specific geometry allows the device to efficiently shear through various dry materials, ensuring a consistent and even texture. A magnetic lid fastens these top components together, keeping the contents securely contained during the manual grinding process and preventing accidental spills.
Integrated Sifting System
Operating as a complete 4-piece setup, the device incorporates a built-in sifting screen directly below the main grinding chamber. This fine mesh layer acts as a mechanical filter, separating larger processed pieces from the smaller, dust-like particles. The finer material naturally falls through the screen and collects in the dedicated bottom pollen chamber, maximizing the utility of the processed botanicals.
Portable Aluminum Construction
Manufactured entirely from metal, this device relies on an aluminum build to provide structural integrity without adding excessive weight. The 2.5-inch form factor strikes a balance between portability and usable capacity, offering enough external surface for user leverage while remaining highly transportable. This design ensures the grinder can withstand regular daily use while easily fitting inside pockets or travel kits.
