Santa Cruz Shredder’s three and four piece grinders are the best all-aluminum grinders—with the sharpest teeth and smoothest threads—we’ve encountered. They come in three sizes. The medium 3 piece grinder (with a 2⅛-inch diameter) was previously a pick in this guide, and it remains a great buy.
Santa Cruz Shredder grinders have a tooth shape that differs from that of every other grinder we’ve evaluated: In our testing we found that its four-pointed teeth worked as well as or better than the diamond-shaped teeth in most grinders.
The grinding plate and teeth are made of the same piece of aluminum, and the metal’s anodized finish has held up well to wear and tear in our long-term testing. Less expensive models, by contrast, often have an unfinished grinding plate that won’t be as durable in the long term.
The holes in this model’s grinding plate are of average size, and they yield a medium-coarse grind that works equally well with most vaporizers, recipes, or pipes. If the teeth ever break, the company stands behind them with a lifetime warranty.
