How to Choose a Herb Grinder — What 30 Years of Selling Them Taught Us

We’ve sold thousands of grinders since 1993. We’ve stocked the good ones, the bad ones, and a few genuinely shocking ones we stopped ordering after the first batch of complaints landed. Here’s what we’ve actually learned.

It almost always comes down to the teeth

The thing most people never think about when buying a grinder is the teeth — and in our experience, it’s the thing that matters most. Cheap grinders tend to have diamond-shaped pegs. They work, sort of. But they push herb around rather than shearing it cleanly, and after a few months the edges round off and you’re basically mashing. The better ones have proper cutting geometry — teeth shaped to grab and cut, not prod and nudge. That’s why a decent grinder usually produces a fluffy, even grind, and a cheap one tends to give you dust at the bottom and chunks at the top. The best tooth designs we’ve come across — the ones on genuinely well-made grinders — are concave with serrated edges. They stay sharper for longer because there’s actual shearing geometry at work rather than just a blunt spike.

The thread problem nobody talks about

This is the one that generates the most complaints, and almost no one mentions it until it happens to them. Cheap grinders tend to strip their threads. It happens because the tolerances are wide, the threads are cut roughly, and people overtighten them — which happens naturally when the grinder gets sticky from use. Once the threads go, the lid spins free or jams solid, and there’s no fixing it. The better-made grinders we’ve found have tapered, self-aligning threads. You don’t have to hunt for the start — the lid seats itself cleanly. You can open and close it with one hand without coaxing. The difference is obvious the moment you pick one up; it feels like a proper bit of kit rather than something that’s fighting you.

Three things we look at before stocking any grinder

Tooth design. Are the teeth genuinely sharp, and are they shaped to cut rather than snag? A grinder with proper geometry should produce a noticeably different result — lighter, more consistent, without hard lumps mixed in with dust. Thread quality. Does the lid seat cleanly without hunting for the thread? On a well-machined grinder this tends to be effortless. If you find yourself fiddling to get the thread to catch, that’s usually the first sign the tolerances are off. Screen and fine pollen/kief catcher (on 4-piece grinders). The screen mesh determines whether your fine pollen/kief builds up usefully over time or disappears as dust. Too coarse and you lose it all; too fine and it clogs quickly. Worth checking the shape of the kief catcher base too — a flat disc you can’t get a card into isn’t much use.

Size matters more than people think

This is the one we find ourselves explaining most often in the shop. A small grinder — under 50mm — is fine for travelling light. For regular use at home, it tends to be frustrating. You’re filling it twice for every session, the magnet is often weaker because the lid is lighter, and there’s almost no kief collection worth talking about. For everyday use, we’d generally suggest 60–62mm minimum. Fill it once, grind it properly, have enough material in the chamber to be useful. In our experience, the medium size is the right call for most people most of the time.

What we stock, and why

Our range covers from the everyday through to the serious. Headchef Razor — our best seller. UK brand, sharp teeth, solid threads, available in a good range of colours. It’s not the cheapest grinder you’ll find, but it’s the one people tend to come back to buy again rather than replacing every few months. The Razor sits in that sweet spot between build quality and price. Headchef Samurai — the step-up. Same 62mm size as the Razor but machined to feel noticeably more solid in the hand. If you’re grinding daily and want something that holds up longer, this is the one we’d usually point you towards.     Santa Cruz Shredder — for when people want the best. American-made, with a tooth design that’s been properly thought through and genuinely feels different to use. In our experience, it produces a fluffier, more even grind than most other metal grinders at any price. If you’ve only ever used mid-range grinders, the difference tends to be immediately obvious. Chongz and acrylic options — we stock these too, and they’re not bad for the money. For occasional use, festivals, or if you don’t want to risk losing a good grinder in a field, they make sense. Just don’t expect the same longevity from daily use.

The upgrade nobody regrets

If you’ve only ever used cheap grinders, the first time you use a properly made one it’s a bit of a moment. The grind is lighter, fluffier, more consistent. It rolls better and behaves more evenly. We’ve had customers come in to replace a cheap grinder after a couple of months. We’ve also had customers ask whether we still stock the same Headchef they bought here eight years ago. Those are two very different conversations, and they tell you everything you need to know.

What’s your favourite grinder?

We’re curious — genuinely. In 30-plus years we’ve seen a lot come and go, and the ones customers stay loyal to aren’t always the ones you’d expect. Drop a comment below: what do you use, and what made you stick with it? Browse our full grinder range →
