Buying Guide
What size should I choose? If you want portability and easy packing, pick a 2-piece model around 2.2 inches. For more capacity, a 3-piece grinder around 2.7 inches works well at home or on the go.
Metal vs. non-metal: Metal grinders offer durability and long life, but some travelers prefer metal-free designs to avoid metal contact with herbs. Consider your comfort with cleaning and maintenance when choosing.
Tooth design matters: Teeth count and shape influence grind consistency. Look for sharp, well-mounted teeth and a pattern designed to produce fluffy, evenly ground material.
Travel considerations: A light, metal-free design or travel-friendly 2-piece models reduce bulk and weight. Secure lids help prevent spillage during transit.
Cleaning and care: Regular brushing and occasional soap-and-water rinses keep teeth clear of plant resins. Dry thoroughly to prevent rust on metal parts.
Made in USA vs. imported: USA-made grinders often emphasize quality construction and longevity. Consider your preference for origin during selection.
