This is the largest Kozo grinder with a classic four-piece layout: a 4 inch body machined from anodized aluminum, with a lid, grinding chamber, storage chamber and kief collection tray. The extra-wide diameter lets you process a lot of herb in one pass, so it is easier to prep for a group or a full week than with a smaller grinder. Diamond-shaped teeth cut the material, a stainless steel screen filters pollen into the bottom tray, and a neodymium magnet keeps the lid secured. A small scraper comes with it for collecting the kief. Nine colors are offered, including Black, Silver, Rose Gold and Multicolor, with the Kozo logo on the lid.
Size is the trade-off here. A 4 inch grinder is a stationary tool, and it is less portable than the smaller options in our 4-part grinders. It pairs well with a bigger container, so a few stash jars are a sensible add-on for storing a larger ground batch. When the threads start to squeak, a tiny drop of food-grade mineral oil on the male threads, wiped clean, helps, and you can find brushes and cleaners among our cleaning tools.
Best for anyone who grinds in volume at home and wants kief separated without extra steps.
