GRAV® 3-Piece Grinder

Engineered from CNC-machined aluminum, the GRAV® 3-Piece Grinder brings aerospace-grade strength and precision to your herb routine. If it’s good enough for astronauts, it’s good enough for your daily grind.

Precision grinding for a bowl-ready finish

Designed with 19 aluminum teeth, this grinder delivers a consistent texture from nug to bowl. The teeth work to break down dry herb into even pieces, while the well-spaced holes let the ground flower fall cleanly into the chamber below—so you get a uniform grind without clogging or mush.

Three-piece design for easy access and clean-up

When your flower is pulverized, it drops into the lower chamber through the deliberate gap pattern. To access the ground material, separate the chambers and use the included GRAV®-branded scraper. Its curved edge fits perfectly into the grinder’s interior corners, helping you sweep every bit of ground herb into your bowl with minimal waste.

Durable, portable, and style-forward

• Material and build: CNC-machined aluminum ensures lasting durability for daily use, while maintaining a lightweight, pocket-friendly profile.
• Color options: Six rich colorways let you pick a look that matches your setup or mood.
• Portability: Comes with a small GRAV® carrying bag for on-the-go sessions, travel-friendly and ready wherever you are.
• Included accessory: The curved GRAV® scraper is designed to reach tight corners, making cleanup quick and minimizing waste.
• 用途: Ideal for preparing cannabis for pipes and bowls, or simply getting your dry herb ready for a clean, even burn.

Who benefits most from this grinder

Perfect for cannabis enthusiasts who value consistent texture and minimal waste, travelers who want reliable performance on the go, and anyone who appreciates durable engineering. If you want a grinder that blends rugged build with a refined grinding action, this GRAV® model from Headshop delivers.

How it stacks up against alternatives

Compared to budget or two-piece grinders, the GRAV® 3-Piece design offers better separation of ground material, easier maintenance, and less risk of jam. The bottom chamber collects the output cleanly, and the included scraper makes cleanup effortless—helping you get more use from every nug.

Tips to get the most from your GRAV® grinder

• Break larger nugs into smaller chunks before grinding to reduce strain on the teeth and achieve a more even texture.
• Grind in short, smooth twists rather than rapid spins to maintain a consistent particle size.
• Separate the chambers after grinding to access the bottom ground material and use the scraper to sweep out any remaining bits.
• Store in the included carrying bag or a protective case to keep the grinder pristine and ready for your next session.

With aerospace-grade craftsmanship, six vibrant color options, and practical features like a curved scraper and carrying bag, the GRAV® 3-Piece Grinder is built to elevate your ritual—one perfectly ground bud at a time.
