Craig Lyn Design Studio · Conical burrCraig Lyn HG-1 Prime
An 83mm Mazzer conical hand grinder from the studio behind the original HG-1, built lighter and easier to crank than its predecessor while keeping the same commercial-grade burr set.
The short version
This is a titan-burr hand grinder shrunk down to something you can actually lift with one hand and stash under a cabinet.
You accept that it is single dose, needs a steady hand and some patience to dial in, and costs about what a decent electric grinder does for the privilege of grinding by arm.
Why people buy it
- Massive 83mm Mazzer conical burrs at hand-grinder size deliver body and clarity most electric grinders in this price range cannot match
- 2.5:1 gear ratio with an extended lever arm makes even light roasts crankable without a bulky flywheel
Why they don’t
- Pure hand tool with no motor, so every dose is manual labor and grinding for multiple drinks back-to-back gets tiring
The full tally
- Massive 83mm Mazzer conical burrs at hand-grinder size deliver body and clarity most electric grinders in this price range cannot match
- 2.5:1 gear ratio with an extended lever arm makes even light roasts crankable without a bulky flywheel
- Compact and light (about 5kg, 31cm tall) so it fits under kitchen cabinets and can be moved with one hand
- Vertical, direct grind path keeps retention very low for a single-dose workflow
- Pure hand tool with no motor, so every dose is manual labor and grinding for multiple drinks back-to-back gets tiring
- Small grind chamber (roughly 25g capacity) makes it impractical for multi-cup pour-over or large batches
- Popcorning and static are present like most conical hand grinders, and dialing in takes trial and error rather than a quick digital setting
What the community knows
Years of owner threads, distilled — strongly recommended.
Unmotorized 83mm conical setup with near-zero retention and heirloom construction—owned by lever-machine specialists and prosumers who prize single-dose workflow and sensory engagement over speed; the steep hand-grind effort (especially light roasts) and steep price tag exclude…

Worth knowing before you buy — Most owners eventually wish they had factored grinding time and effort into the decision earlier—it's not a "set and forget" purchase even after you own it.
Known weak points — None documented in community record; original 2014 models still in daily use.

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners coming from entry electric grinders or smaller hand grinders (Comandante, Timemore) upgrade into the HG-1 Prime for the big 83mm conical burr cup quality; those who eventually want a motor tend to look at Weber Workshops' HG-2 or Key, or a motorized WUG-style conversion, rather than staying fully manual.

Before it arrives
What completes this grinder — the faded pieces can wait.
Coffee scale with timer — Espresso is a ratio. A 0.1g scale with a built-in timer is the single biggest consistency upgrade for any manual machine.

- Dosing cup — Pairs with single-dose grinding — grind into the cup, swirl, and transfer to the portafilter cleanly.
- Grinder cleaning kit — Brushes and grinder tablets keep retention and stale grounds in check.
Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. These burrs pull syrup — naturals and classic medium roasts play straight into their character.

Worth comparing
Timemore
Sculptor 078S
A 78mm flat-burr single-dose grinder that Timemore built to do espresso and filter from one machine, with variable RPM and a rotary knocker instead of a bellows. It looks the part and grinds cleanly, but the narrow espresso adjustment window and fiddly burr access mean it rewards patience more than plug-and-play.
