Toothless Grinders: What They Are, How They Work, and Whether They’re Worth It
Nearly every grinder we’ve sold in thirty-odd years has had teeth in it. Little diamond-shaped pegs that shred the material as you twist. They work, they’ve always worked, and they’re what everybody pictures when you say the word grinder.
They also bend. They clog. Snap one tooth off a cheap one and the whole thing binds up. And anyone who’s ever sat there with a pin picking compacted bits out of the teeth knows exactly what we mean.
Over the last couple of years a different sort has turned up, and this year we’ve ended up with four of them on the shelf. No teeth at all. Here’s what they actually are, what difference it makes, and where it doesn’t.
What a toothless grinder actually is
Instead of pegs, the two halves carry a machined pattern — shaped surfaces, wave profiles, interlocking recesses, depending on who made it. When you turn the lid, those surfaces press against each other and the material gets crushed and folded between them rather than torn apart.
The patent behind the idea puts it neatly: it uses friction instead of sharpness. Closer to a mortar and pestle than a blade.
That’s the whole thing. It’s not a gimmick and it’s not marketing — it’s a genuinely different mechanical action, and it has knock-on effects worth knowing about.
What difference it makes
The grind comes out fluffier. Teeth tear, which produces a mix of over-shredded dust and untouched lumps. Crushing breaks material along its natural structure, so you get a more even, open texture rather than powder.
Less heat. No sharp edges dragging through means less friction, and less friction means less warmth going into what you’re grinding.
Nothing to break. This is the one people underestimate. There are no teeth to bend, snap or clog, because there are no teeth. The failure point of a cheap grinder simply isn’t there.
Cleaning takes seconds. Smooth machined surfaces wipe out. Anyone who’s tried to get a toothed grinder properly clean — and we sell grinder cleaner precisely because people struggle — will appreciate the difference.
Less effort to turn. Worth saying plainly: there’s no snagging and no resistance, so you’re not wrestling with it. If grip strength is a factor for you, that matters more than any of the above.
The honest downside
Two things.
First, a very fine grind can clog some vaporisers. If you’re running a dry herb vape and you like it packed loose, check what your machine prefers before you switch.
Second, and more simply — toothed grinders are not broken. A good 4-part metal one like the RAW Stainless Steel 4-Part or a Santa Cruz Shredder will do you twenty years. Toothless isn’t an upgrade everybody needs. It’s a different approach that suits some people better.
The four we stock
Headchef Vortex 62mm 5-Piece — £35
Headchef’s own line on it is “no teeth, that’s the whole point”, which saves us explaining it. Ceramic-coated grinding chamber and storage bowl, fine mesh screen for the pollen, and a screw-top compartment built into the top so you can carry ground and unground in the same unit. Cheapest way into the category and a sensible first one.
Headchef Vortex 62mm 5-Piece Grinder — or see the rest of the Headchef grinder range.
V Syndicate 72mm Gridlock Toothless — £39.99
Seventy-two millimetres, which makes it the biggest grinder in the shop full stop. A patterned gridlock plate does the work where the teeth would be. If you grind for more than yourself, or you just resent doing it twice, the extra diameter is the point.
V Syndicate 72mm Gridlock Toothless Grinder
Calvo Aura 63mm Non Teeth — £49.99
A machined wave profile folds and separates between shaped surfaces rather than shredding. Full-size at 63mm, aerospace-grade aluminium, neodymium magnet holding the lid, mesh screen into a bottom collector, and a separate sealed storage section on top. Comes with a guitar-pick scraper in a printed presentation tube rather than a bag of plastic.
It’s the one that feels most obviously engineered when you pick it up.

RAW Buddy Mill 60mm 3-Piece — £49.99
The odd one out, and the most interesting. RAW have used a stainless-steel milling plate system where the teeth would normally be — the same action as an old-fashioned spice mill. Three pieces, strips down in seconds.
The part nobody else does: the milling plate is interchangeable. Swap it and you change the particle size. Every other grinder on this page — every other grinder in the shop — gives you whatever grind the manufacturer decided on. This one doesn’t.

Which one, if you’re asking
If you want to try the idea without spending much, the Vortex at £35. If you grind in bulk, the 72mm V Syndicate. If you want the nicest object, the Calvo Aura. If you care about controlling the grind itself, the Buddy Mill, because none of the others let you change it.
And if none of that appeals, that’s a perfectly reasonable conclusion — the toothed stuff has worked for decades and we’ve got about forty of them. Metal grinders, acrylic and plastic, wooden, and pollen presses for what ends up in the bottom chamber.
For the broader question of sizes, parts and materials, we wrote that one up already: How to Choose a Herb Grinder.
Come and turn one
All four are out on the counter at 13a Lowthian Street. You can pick them up, turn them, and feel the difference against a toothed one in about three seconds — which is a lot more use than reading about it.
Or order online and we’ll post it out, same as always.
