Sharpstone is one of the few grinder brands New Zealand buyers search for by name rather than by description. The bodies are cut from aircraft-grade aluminium rod on CNC machinery and then anodised, which is why they resist the smudging and wear marks that show up on cheaper cast bodies.
What is in a Sharpstone grinder
-
Machined aluminium body. Cut from solid rod rather than cast, then anodised for the finish.
-
Diamond-cut blades. Machined teeth that cut rather than tear.
-
Stainless steel pollen screen. On the 4 piece models, a stainless mesh sieves the fine powder into the bottom chamber. Stainless survives cleaning better than plated mesh.
-
Neodymium magnet lid. Holds the lid closed while the grinder is turned.
-
Poly friction ring. A thin polymer ring around the top grinding section so the two halves turn smoothly against each other instead of metal on metal.
-
Pouch and scraper. The premium models are supplied with a protective pouch and a scraper for the kief chamber.
These specifications come from the product listings and Sharpstone's own description of the range.
Which Sharpstone
Greenhut carries the Sharpstone premium series and the Sharpstone V2. The V2 is the redesigned generation, with revised ergonomics and added anti-counterfeit features over the original. The clear-top model swaps the solid lid for a transparent one so you can see the grinding chamber without opening it. Check the diameter and piece count on each product page — the range covers both 4 piece and smaller builds.
Sharpstone or an unbranded alloy grinder?
You are paying for the machining and the materials: a rod-cut anodised body, a stainless screen and a poly friction ring, versus a cast zinc alloy body with a plated screen. If you use a grinder daily, that is where the difference shows. If you want a spare, or a first grinder, the wider metal grinder range covers it for less.
Watch out for counterfeit Sharpstone units sold online — buying from a New Zealand retailer that stocks the range is the simplest way around it. For how Sharpstone compares to the rest of the market, read Herb Grinders 101 — the complete NZ buying guide, or browse all herb and herb grinders.
