Why we picked it
CNC-machined from 6061-T6 anodized aluminum (vs cast / pressed)
Santa Cruz Shredder is the herb grinder r/Trees, r/EDC, and r/PipeTobacco consensus recommend as the lifetime grade pick over the no name aluminum grinders that pop teeth and strip threads within months. The body is CNC machined from 6061-T6 anodized aluminum (vs the cast / pressed aluminum of cheap grinders), the magnetic top closes positively without thread issues, and the teeth are precisely cut at angles that produce uniform fluffy grind that competing brands can't match. r/Trees frequently runs 'what grinder' threads where Santa Cruz Shredder ranks top across user polls. Made in Santa Cruz, CA, lifetime replacement of any structurally failed grinder.
