Types of weed grinders

• 2-piece: a lid and a grinding chamber with no screen, such as the ONGROK 2-Piece Walnut Grinder.
• 3-piece: adds a collection chamber below the teeth, such as the Cipher Ultra 3-piece.
• 4-piece: adds a screen and a kief catcher at the bottom, such as the TRĒ House 4-Piece Aluminum, ONGROK 4 Piece EZ and RYOT 4pc Jar Body grinders.
• 5-piece and storage grinders: add an extra storage section, such as the ONGROK 5 Piece Storage and Pulsar Metal Storage and 4-Piece grinders.
• Electric: the Pulsar King Kut grinds with a motor instead of by hand.

What to look for in a grinder

• Material: anodized aluminum is light and common; stainless steel is heavier and hard-wearing; wood (maple, walnut, rosewood) gives a classic look.
• Diameter: sizes run from pocket models around 2 inches to 4-inch grinders such as the Kozo 2.5, 3 and 4 Inch models.
• Teeth design: diamond-shaped teeth, blade-style mills and toothless designs grind differently, from fine to coarse.
• Kief screen: 4- and 5-piece grinders collect fine trichomes in a bottom chamber.
• Window or jar body: see-through bodies, like the RYOT GR8TR Jar Body and Kozo Window, show the ground material.

Weed grinder FAQ

What does a kief catcher do?

A fine mesh screen lets small trichomes fall through into a separate bottom chamber, where they collect over time.

Are electric grinders different from manual ones?

Electric grinders use a battery-powered motor to turn the blades; manual grinders are twisted by hand.
