A quality grinder can save you time and effort when you’re preparing cannabis. To quickly and easily process dried flowers into ground material to pack into a vaporizer or to use in a recipe, we reach for the Kannastör Gr8tr Jar Body Grinder.
Compared with lesser models, it grinds finely, smoothly, and evenly, producing consistent results with both its coarse and fine grinding plates. A reliable grind means smoother smoking or vaping. And the Gr8tr has a transparent storage container that can stash up to a full eighth of an ounce of flower.
Our pick
Kannastör Gr8tr
In our tests, this aluminum grinder produced the fluffiest and finest results. Its bonus storage compartment and an optional plate for coarser grinds are unique extras worth the added cost.
The small, sharp teeth inside the Kannastör Gr8tr Jar Body Grinder tear through cannabis smoothly without binding. And compared with those of the similarly priced models we tried, the Gr8tr’s teeth dropped the finest and fluffiest material into the collection chamber. That’s ideal for use in many vaporizers, especially conduction-based models or hybrid conduction-convection models. (If you have a convection vaporizer, you can unscrew the Gr8tr’s fine-grind plate and replace it with the included coarse-grind option.)
This grinder comes with a mesh screen for catching the ultrafine (and highly potent) cannabis particles called kief. Without adding bulk, the Gr8tr’s topmost piece seals off an extra storage compartment that no other grinder we considered includes—it’s a great place to store a hefty amount of whole flowers or ground product that you can enjoy later. Since the stash jar is transparent, you can easily eyeball how much material you have handy.
Also great
Santa Cruz Shredder Medium 3-Piece Shredder
This simple aluminum model offers reliably smooth grinding thanks to sharp, uniquely shaped teeth. The collection chamber can fit up to an eighth of an ounce of flower and has rounded sides that make it easy to empty.
In our tests, the four-pointed teeth on the Santa Cruz Shredder Medium 3-Piece Shredder quickly and easily broke apart sticky, closely packed flowers. Its uniform grind makes for a mellow, smooth smoke. The three-piece model we recommend is easy to empty little by little thanks to its rounded bottom; it’s far less messy than dumping a grinder out to get at something stuck in the corners. The pieces of Santa Cruz’s grinder—which is also available in a four-piece version with a mesh kief catcher, as well as in larger or smaller sizes—easily thread together, and the top glides smoothly as you twist it.
Upgrade pick
Herb Ripper The Ripper XL Herb Grinder
A great choice for processing lots of cannabis (including stickier flower), this hefty model is potentially easier on hands, fingers, and wrists, as embedded magnets make its grinding motion extra smooth.
If you routinely grind large quantities of super-sticky strains, investing in an all-stainless steel grinder may be worth the added expense. Herb Ripper’s The Ripper XL Herb Grinder, available in three- or four-piece sets, is an absolute pleasure to use–and easy to keep clean. Embedded magnets help make the grinding process feel especially smooth. The Ripper XL feels weighty in the hand, and its simple design omits extra bulk.
