Grinder

A grinder breaks flower into even particles, and evenness is the entire point: consistent grind means consistent airflow, even extraction in a vaporizer, and pre-rolls that burn straight. The market splits into cheap multi-piece metal grinders (fine for most people), premium machined units with sharper teeth and better tolerances, and single-purpose card-style graters for travel. Kief catchers — the screen-and-tray bottom stage — accumulate loose trichomes worth keeping. Honest spend guidance: a mid-priced metal grinder is the right answer until a specific complaint (fluffy grind for convection, resin binding) names the upgrade.
