When it comes to cannabis accessories, few names spark as much conversation as Kannastor. Produced by RYOT, the grinders in this line are known for their modular design, durable aluminum construction, and customization options that appeal to both casual consumers and seasoned enthusiasts. Unlike standard grinders, Kannastor builds products with interchangeable pieces, giving users more control over grind consistency and functionality.
Featured Models
- Kannastor GR8TR V2 Jar Body Grinder – ($63.99, eBay) A flagship design with modular plates, a transparent jar body for storage, and the signature GR8TR grind system.
- Kannastor Pendant Grinder – ($21.99, Smokea) A compact option that doubles as a necklace, meant for on-the-go convenience.
Build and Aesthetic
Kannastor grinders are machined from high-grade anodized aluminum, which helps them remain lightweight yet tough against wear. The GR8TR line, in particular, showcases the brand’s focus on modularity. Instead of a fixed setup, you can remove or swap pieces: run it as a full four-piece grinder with kief screen and jar body, or slim it down into a more travel-friendly version. This level of flexibility is something you won’t see with most competitors.
Visually, Kannastor devices balance industrial toughness with clean lines. Jar versions allow you to see the ground flower through a transparent chamber—practical when you want to check quantity without disassembly.
Grind Performance
Performance is where Kannastor earns its reputation. The GR8TR V2 comes with two interchangeable grind plates—one fine, one medium. The fine plate delivers powdery herb that works well in vaporizers, while the medium plate produces fluffy consistency ideal for rolling joints or packing bowls. The stubby teeth design provides less resistance, making it easier to twist without jamming.
However, this versatility does come with trade-offs. Some users find the fine grind too powdery for smoking, and the taller, modular build isn’t the most pocket-friendly. If portability is a top priority, the Pendant Grinder or a slimmed-down GR8TR configuration might be better.
Cleaning and Durability
Durability is a highlight, thanks to the anodized finish that resists scratches and corrosion. But maintenance requires attention. With multiple threaded sections and removable plates, residue can build up more quickly than in a simple two-piece grinder. Regular cleaning is essential to keep performance smooth. Thankfully, the removable kief screen makes cleaning and replacement easier than many competitors allow.
Pros and Cons

Overall Impression
Kannastor grinders cater to users who appreciate customization and precision. The GR8TR V2 is more than just a grinder—it’s a toolkit for tailoring grind size, storage, and style. For those who primarily use vaporizers or enjoy collecting high-end accessories, it’s a worthwhile investment. On the other hand, if you want something simple, portable, and maintenance-free, a basic two-piece might suit you better.
In short, Kannastor delivers flexibility and craftsmanship that stand out in a crowded grinder market, but the experience is best suited for those willing to maintain and explore its modular potential.
