Aluminum 2 Piece Small Herb Grinders

I got the small size. Perfect for a day trip as it is small, very small. About the size of a Silver dollar.
Work excellent, highly recommended

The size makes it a little slippery, but still workable with some pressure.

Deeper serration, or small lugs would go a long way for this tiny grinder.. Currently, its very difficult to turn, my wife struggles with it.
There is serration along 1 side, why not both?

That being said, its solid and it does grind. And as I use a dry herb vape, I barely grind anyway.
It will work well for me in the backcountry, durable, brightly colored, and light enough.

Pls add lugs/better grip.

This thing was dinky and too hard to shred even a tiny bit of herb. Very disappointed

I am impressed with how well engineered it is. I thought it would hurt my arthritic hands but it didn't. It doesn't require much torque to twist it and it doesn't require many twists to break up the weed.
