Sharpstone V2 4 Piece 2.5" Grinder

Sharpstone V2 4 Piece 2.5" Grinder — At a Glance

A full-size 2.5-inch, four-piece herb grinder from Sharpstone's V2 line — CNC-machined aircraft-grade aluminum, razor-sharp diamond-cut teeth, a stainless steel pollen screen, and a bottom kief chamber. Includes a kief scraper and storage pouch. Choose Black, Blue, Green, or Red.

Who it's for

• Daily grinders who want a large-capacity 2.5" body that handles big loads in one twist.
• Kief collectors — the 4-piece design with stainless mesh screen separates and stores pollen in the bottom chamber.
• Anyone replacing a worn plastic or dull grinder — the V2's anodized aluminum and diamond teeth are a durability upgrade.

What "4-piece" means

• Lid (top) — magnetic, keeps everything sealed.
• Grinding chamber — diamond teeth shred herb as you twist.
• Collection chamber with holes — ground herb falls through here.
• Kief catch (bottom) — a stainless steel screen lets pollen sift down into this chamber for later use.

Features

• Aircraft-grade aluminum body, CNC-machined for precise threading.
• Anodized finish resists wear, smudges, and corrosion.
• Diamond-cut grinding teeth for a fast, even grind.
• Stainless steel pollen screen sized to pass only fine kief.
• Neodymium magnet in the lid for a secure, rattle-free close.
• Poly friction ring on the top section for a smooth twist.
• 2.5" diameter — large capacity.
• Includes a pollen/kief scraper and a protective storage pouch.

How to use it

1. Unscrew the lid and break herb into pea-sized pieces around the teeth (avoid the center post for an even grind).
2. Replace the lid and twist back and forth ~8–10 times.
3. Open the grinding chamber — ground herb sits in the collection chamber below.
4. Over days of use, kief sifts through the screen into the bottom chamber. Scrape it out with the included tool when you want a potency boost.

Care

• Tap the grinder to knock loose herb down before opening to reduce mess.
• Clean periodically: freeze for ~30 min, then brush/tap the teeth and screen. For a deep clean, soak aluminum parts (not the screen gasket) in isopropyl alcohol, rinse, and dry fully.
• Don't force a stiff twist — a quick freeze loosens sticky resin buildup.

FAQ

How big is it? 2.5" diameter — a full-size grinder, larger than the common 2" / 2.2" pocket sizes.

Does it collect kief? Yes — the 4-piece design has a stainless screen and a dedicated bottom chamber for pollen, plus a scraper.

Is it magnetic? Yes — a neodymium magnet holds the lid closed.

What's the difference from the non-V2 Sharpstone? The V2 line uses updated diamond-cut teeth and the poly friction ring for a smoother grind.
