Micro-Teeth & MTP Technology

The proprietary Micro-Teeth and Dish Press (MTP) design results in effortless grinding. The Dish Press increases torque, allowing users with restricted hand and wrist movement to grind away easily. This is great for users with medical conditions and less physical strength.

Interchangeable Grind Plates

Kannastor includes a number of interchangeable plates that suit different preferences. These patent pending plates help you customize the consistency of your grounds. It doesn’t matter if you're grinding your material to smoke or to use in a vaporizer, the GR8TR has you covered with the perfect grind plate.

Easy Change Screen

Focusing on creating the most advanced, versatile herb grinder, Kannastor has also incorporated an easy change screen into the GR8TR. This design allows the user to easily remove the sifter screen and replace if with one of the four mesh styles available. Simply, this means the user can again customize the grinder to suit their personal preference.
