Metal vs Acrylic vs Wood Grinders: Complete Material Comparison 2026

Choosing a cannabis grinder starts with material selection. Metal, acrylic, and wood grinders each have distinct advantages and drawbacks. This guide compares all three materials to help you find the perfect grinder for your needs and budget.

Quick Answer

Metal grinders (aluminum/titanium) are best for durability, sharp teeth, and long-term value ($20-60, lasts 5-10+ years). Acrylic grinders are cheapest ($5-15, lasts 1-2 years) but teeth dull quickly. Wood grinders look beautiful ($20-40, lasts 2-4 years) but require maintenance and can absorb odors. For most users, metal is the clear winner.
