3 Piece vs. 4 Piece Herb Grinder - What is the difference?

A 3 Piece Herb Grinder without the middle chamber is a bit shorter in height, giving it a slight advantage in packability. A 4 Piece Herb Grinder lets you easily separate your ground herb from your kief. It uses an additional chamber containing a thin mesh screen that only allows the kief to pass through into the kief catcher.


What is a kief catcher?

A kief catcher is the bottom chamber in the herb grinder below the screen. It collects trichomes to be used separately from or in combination with ground herb.
