Aluminum Grinders
Built like an heirloom.
Precision-milled aircraft-grade aluminum. Heavy in hand. Buttery on the spin. From $59.99.
Buy once. Grind forever.
Aluminum is the move when you want a grinder that outlives every plastic you've ever owned. CNC-milled from aircraft-grade billet, anodized so the color won't chip, and weighted just enough that it feels expensive in your hand. Same diamond-cut teeth, same magnetic lid, same kief catcher — just upgraded everywhere it counts.

Shop Plastic →Aluminum herb grinders built for decades
The aluminum HerbSaver is our heirloom grinder: precision-milled from aircraft-grade aluminum with an anodized finish, a magnetic lid, diamond-cut teeth, a mesh screen and a kief catcher. It's heavier in the hand, smoother on the spin and covered by the same lifetime warranty as every HerbSaver.
Metal or plastic?
Our plastic grinders are light, colorful and affordable. A metal weed grinder is for people who want one grinder for life: it won't crack, and it feels solid every time you twist it.
Limited metal editions
Beyond the classic Large Aluminum grinder, we drop printed metal editions like the Halloween collection and the RiFF RAFF Jody Highroller. They're small runs that don't restock.
How do I clean an aluminum grinder?
Take it apart, soak the metal pieces in warm soapy water, scrub the teeth and screen with a soft brush and dry completely before reassembling.
What are HerbSaver aluminum grinders made of?
CNC-milled, aircraft-grade aluminum with an anodized finish, so the color won't chip.
Will an aluminum grinder flake?
Quality anodized aircraft-grade aluminum is built to hold up. Flaking usually comes from cheap zinc-alloy grinders.
Does the aluminum grinder have a kief catcher?
Yes. It has the same diamond teeth, magnetic lid and kief catcher as our plastic 4-piece grinders.
