Curves in All the Right Places

Experience a grinder designed for your hand, not just your table. The Human Grade Metal Grinder (Curved Body) redefines comfort with its unique hourglass shape. This ergonomic curved body fits naturally in your palm, giving you superior leverage and control to crush through dense herbs without straining your wrist.

But this piece is more than just a grinder—it’s a portable station. The top lid features a concave design that functions as a Built-In Ashtray. This clever addition keeps your session tidy, giving you a dedicated spot to ash your roll or rest your cone, no matter where you are.

At 2.5 inches (63mm), it offers the perfect capacity for daily use. Precision-engineered from durable aluminum, this 4-Piece System shreds your material to a fluffy consistency while filtering fine pollen through a premium screen into the bottom catch. Smart, comfortable, and clean—it’s the Human Grade standard.

Frequently Asked Questions: Curved Grinder

How does the ashtray work?

The top surface of the magnetic lid is concave (dished) rather than flat. This creates a small bowl shape that is perfect for ashing a joint or holding your rolling papers while you prep, effectively turning the grinder into a mini rolling tray.

Does the curved shape help with grinding?

Yes. The curved/notched body allows your fingers to wrap around the grinder more securely than a smooth cylinder. This gives you better leverage (torque) when twisting, which is especially helpful for sticky or dense herbs.

Is it easy to clean?

Like all Human Grade aluminum grinders, it is very low maintenance. If it gets sticky, a quick soak in Isopropyl Alcohol followed by a warm water rinse will make it look brand new.
