The RAW Life Grinder is engineered to last a lifetime. Constructed of Aircraft-Grade Aluminum-Magnesium Alloy with a strength of 18,000 PSI, this grinder can stand up to anything. Each piece comes apart for easy cleaning, allowing the RAW Life Grinder to be completely modular and customizable. Go from a four to a two-piece grinder in seconds. The teeth are not anodized, so they stay sharp with extended use and, there is no chance the coating will flake off and end up in your smoking material. RAW stands behind the grinder for life. If any of the individual pieces wear out from normal use, RAW will replace it free of charge.
