Our 4-Piece 2.5” Stainless Steel grinder is a favorite among our customers! After receiving so many positive reviews and experiences from our already proven 1.75” mini herb grinder, we wanted to create a larger version with the same quality and performance. This durable and sleek 4 part grinder is perfect for larger dosing and makes a positive impression on friends during a group sesh! Best Part? You can load more herb into the grinding chamber! 

The weight and feel of this big herb grinder is durable and heavy duty. Unlike aluminum grinders, it is constructed of 100% medical grade stainless steel, making it ideal for medical patients and anyone who has health concerns using aluminum products.  

This large grinder with a kief catcher is built with the same design methods and technology used in aerospace and renewable energy fields. It is high quality, guaranteed to perform and last a lifetime.

This 4 piece grinder features our Patent Pending labyrinth seal design. With our exclusive labyrinth seal solution, the top and middle pieces of the grinder are specially sealed together so your herb stays securely inside – no spills and no lost herb to worry about.

Create the perfect grind with just a few turns of the grinder. Sharp diamond-shaped teeth will cut and grind your herb with ease, and knurled top and bottom pieces save you from excessive wrist strain.

This four piece grinder includes a kief catcher or pollen catcher that functions as a storage compartment for collecting kief.


A kief screen is a type of sift screen used to separate ground herbs from kief. An ultra fine stainless steel mesh screen allows the trichomes to pass through to the bottom chamber, while the bigger herb pieces remain in the catch chamber.

Our 4 piece grinder with a kief catcher features a sift screen and catch chamber on the bottom to collect those potent trichomes that fall off during the grinding process. The stainless steel sift screens are removable, allowing you to choose between fine and medium micron sizes. 

You can sprinkle these trichomes on top of a bowl, in a joint, or use it in cooking and baking your favorite meals and treats! 

The bottom chamber may double as a stash container for ready-to-go ground flower. Elevate your experience by upgrading to the best large 4 chamber grinder!

    We originally started with a 1.5" aluminum four piece and I have to say that this is a big step up from that. It grinds easily and I have wrist issues. It might stick occasionally but a little back and forth makes it through. The reasons for 4-stars are small but noticeable. First, the threads are very short. We know now but almost spilled a few times because it takes one turn to undo it. Plus we almost cross-threaded it a few times. Second, there are some longer holes around the inside edge of the grinder. The grind comes out nice, medium, and fluffy but with the holes, we sometimes get larger chunks that have squeezed through the holes that are about 5x larger than the smaller ones that are on the inner part of the grinder. Other than those things, it's super easy to clean, (small threads sometimes accumulate powder and we use a pick to clean them), beautiful grinder overall, all my friends are fans, and it's the only one I'll ever use again.

    Last grinder

    Published by Paul Skeffington on Oct 4th 2020

    This is the last grinder you will ever buy, unless you grab the personal. This thing is perfect for wrapping full sized blunts. A drop of hemp seed oil along the rim, and this grinder feels glass smooth. The kief holder is over sized and is perfect for storing bubble kief. Could not recommend more!
