• 2-piece grinders (lid + teeth chamber) are simple and compact, ideal for small sessions.
• 3-piece grinders include a middle section that collects ground herb.
  
• 4-piece grinders add a fine mesh screen and base chamber to collect kief (fine crystal dust).
  
  If you enjoy saving pollen, a 4-piece model is worth the upgrade.

• Aluminium or stainless steel: most durable, consistent grind, long-lasting.

• Acrylic/plastic: lightweight and cheap but wear faster.
  
• Wood: unique look, smooth grind, but less precise.
  
  For most Australians, metal grinders are the top pick for longevity and smooth rotation.

Sizes range from 40 mm (pocket-friendly) to 63 mm+ (home use).

If you mostly roll joints or use a vaporiser, a 50–55 mm is a perfect all-rounder.

Larger grinders are ideal for bulk prepping or multiple users.

Kief is the fine, powdery resin that falls off the herb during grinding.

A kief catcher or mesh screen in a 4-piece grinder collects this material so you can sprinkle it later for extra strength. It’s a feature valued by experienced users.

Joints/cones: medium grind — burns evenly and doesn’t clog.

Pipes/bongs: slightly coarser — avoids pulling fine bits through.

Vaporisers: fine but not powdery — more surface area = better vapour extraction.

Yes — herb grinders are sold legally nationwide as tobacco or herbal smoking accessories.

However:

• You must be 18 + to buy them.
  
• Do not advertise or label them for cannabis use — use “dry herb,” “herbal,” or “tobacco grinder” in listings.
  
• Some states (e.g. QLD, SA) have specific restrictions on “drug paraphernalia” advertising, so keep descriptions neutral and compliant.

Look for:

• Sharp, diamond-shaped teeth
  
• Magnetic lid
  
• Smooth threading
  
• Kief screen and scraper
  
• Non-stick coating (optional)
  
  These improve efficiency, prevent sticking, and ensure an even grind.
  

Specialty smoking accessory retailers and online stores like We Are Lux sell grinders in a range of sizes and materials.

Brush or tap out residue regularly. For deeper cleans:

1. Freeze for 30 min to loosen sticky resin.
   
2. Use isopropyl alcohol and a toothbrush for metal grinders.
   
3. Rinse, dry fully before reassembling.
   
   Avoid soaking acrylic or wooden grinders in alcohol — it can damage them.

Yes. Uneven or dull grinders can shred rather than slice, bruising the herb and releasing moisture unevenly. A sharp-toothed metal grinder keeps trichomes intact for better flavour and potency.
