Kannastor Grinders

herb grinder should be.

Whether you're a joint, packing a bowl, or prepping for a vaporizer session, Kannastor offers the perfect grind every time, thanks to its unique design, replaceable components, and industry-first modular approach. Built to last, designed to perform, and engineered for daily use, Kannastor is more than a grinder—it's a complete flower prep system.

The GR8TR Grinder – Kannastor's Innovation

The Kannastor GR8TR Grinder (pronounced "Grater") represents the pinnacle of grinding technology. More than just a multi-chamber grinder, the GR8TR is a fully modular herb grinding system that adapts to your needs. Whether you want a fine grind for vaporizing or a coarser consistency for rolling, the GR8TR delivers unmatched precision.

Modular Design

The GR8TR can be easily customized with interchangeable grinding plates to suit your preferred consistency. Swap between fine and coarse plates depending on your cooking—there is no need for multiple grinders.

Micro-Teeth Engineering

The GR8TR's patented Micro-Teeth ensure a consistent, fluffy grind without clumping. Unlike traditional grinders, it gently slices your flower instead of crushing it, preserving potency and avoiding resin buildup.

Vape-Ready and Roll-Ready

Whether you use a desktop vaporizer, dry herb vape pen, bong, or blunt, the GR8TR gives you the control to tailor your grind exactly to your device. It is perfect for connoisseurs who care about airflow, burn consistency, and terpene retention.

Replaceable Screens and Plates

Most Kannastor herb grinders feature easy-to-replace mesh screens, which make long-term maintenance and straightforward use more sustainable. The GR8TR includes a pollen chamber with a kief collection screen that can be swapped out when needed.

Portable and Discreet

The GR8TR V2 offers a sleek form factor, a magnetic lid, an easy-grip texture, and a convenient storage compartment. It's the go-to SL grinder for daily carry or home use.
