Feldgrind: The Hand Grinder That Started a Movement
The Knock Feldgrind is one of those products that coffee nerds whisper about in online forums and Facebook groups. Built by a small Scottish company called Knock, the Feldgrind helped prove that a hand grinder could produce espresso-quality grinds, not just decent drip. It was a big deal when it launched, and it still holds up against newer competitors.
If you're here because someone on Reddit recommended the Feldgrind, or you found one for sale and want to know if it's worth grabbing, here's what I've learned after using one for over a year. I'll cover grind quality, build, the quirky ordering process, and how it compares to newer hand grinders that have entered the market since.
What Makes the Feldgrind Special
The Feldgrind uses 47mm Italmill steel burrs, which were some of the best available in a hand grinder when it launched around 2015-2016. These are the same burrs used in some commercial grinders, scaled down for manual use.
What set the Feldgrind apart from other hand grinders at the time was its ability to grind fine enough for espresso with good consistency. Most hand grinders in that era (Hario Skerton, Porlex) could reach espresso fineness but produced too many fine particles and boulders to pull a decent shot. The Feldgrind's tighter tolerances and quality burrs changed that.
The grind adjustment is stepless, using a ring at the base of the handle. You turn it to adjust, and there are no clicks or detents. This gives you infinite precision but also means you need to keep track of your setting manually. Some people mark their preferred position with a dot of nail polish.
The "Knock" Experience
Buying a Knock grinder is an experience in itself. The company is essentially one person (Peter Knock) making grinders in Scotland and selling them in limited batches. The Feldgrind has historically been difficult to buy because stock sells out quickly and restocks are irregular.
Ordering typically happens through the Knock website, and you might wait weeks or months for a batch to become available. This scarcity has created a secondary market where used Feldgrinds sell for close to retail price, sometimes more.
Grind Quality
I've tested the Feldgrind across multiple brew methods, and here's what I found.
Espresso
The Feldgrind can absolutely grind for espresso. The particle distribution is tight enough to pull balanced shots without excessive channeling. Is it as consistent as a $1,500 Niche Zero or Eureka Atom? No. But for a $120-$160 hand grinder, the results are impressive.
Dialing in for espresso with the stepless adjustment takes patience. Small turns make significant changes at the fine end. I spent about 15 minutes and 4-5 wasted shots finding my sweet spot when I first started, but once I marked the position, I could return to it reliably.
Pour-Over and Filter
For pour-over, the Feldgrind produces a clean, even grind that makes V60 and Chemex brewing straightforward. The grind quality at the medium settings is comparable to electric grinders in the $200-$300 range, which is a strong claim for a hand grinder at this price.
French press at the coarser end is good, though I noticed a few more fines than I'd prefer at the coarsest settings. This can make French press cups slightly cloudier, but the flavor is still excellent.
Grinding Speed
Grinding 15-18 grams for espresso takes about 35-45 seconds. That's faster than a Porlex or Hario but slower than newer hand grinders like the 1Zpresso JX-Pro or Comandante C40, which can do the same in 25-30 seconds. The handle is comfortable and the grinding action is smooth, so it doesn't feel like a workout.
Build Quality
The Feldgrind has a distinctive look. The body is anodized aluminum available in several colors (black, red, silver, blue, and others depending on the batch). It's compact, about 7 inches tall and 2 inches in diameter. Weight is around 15 ounces.
The build feels solid without being overly heavy. The aluminum body is well-machined, and the tolerances are tight. There's no wobble in the central shaft, which directly affects grind consistency. The catch cup screws onto the bottom and holds about 25-30 grams of ground coffee.
One criticism I have: the catch cup threads can be slightly finicky. If you cross-thread it even a little, it binds. After a few uses, I developed the muscle memory to thread it on straight, but it's something to be aware of.
Feldgrind vs. Modern Hand Grinders
The hand grinder market has exploded since the Feldgrind launched. Here's how it compares to the current favorites.
Feldgrind vs. Comandante C40
The Comandante C40 ($250-$280) is the current gold standard for hand grinders. It uses proprietary high-nitrogen steel burrs that produce exceptional grind consistency across all settings. The C40 beats the Feldgrind on grind quality, build refinement, and availability (though Comandante has its own stock issues). The Feldgrind costs significantly less, so if you're budget-conscious, it still offers strong value.
Feldgrind vs. 1Zpresso JX-Pro
The 1Zpresso JX-Pro ($160-$180) is the hand grinder I'd recommend to most people right now. It uses 48mm steel burrs with a fast grinding speed and an external adjustment dial that's easier to use than the Feldgrind's system. Grind quality is comparable, with the JX-Pro having a slight edge in consistency at espresso settings. The JX-Pro is also much easier to buy.
Feldgrind vs. Timemore Chestnut X
The Timemore Chestnut X ($200) uses S2C steel burrs and has been getting excellent reviews. It grinds faster than the Feldgrind, has a more refined build, and includes a carrying case. For the small price difference, the Timemore is a strong choice if the Feldgrind isn't available.

Who Should Buy a Feldgrind in 2026?
This is the honest question. The Feldgrind was a groundbreaking product when it came out, and it's still a good grinder. But the market has caught up, and in some cases surpassed it.
You should consider a Feldgrind if:
- You find one at a good price (under $130) on the used market
- You want a compact, well-made hand grinder that handles espresso through pour-over
- You appreciate the small-batch, artisanal story behind Knock as a company
You should probably skip the Feldgrind if:
- You want something you can buy today without waiting for a restock
- You value ease of adjustment (the stepless ring is less user-friendly than external dials)
- You want the absolute best grind quality in a hand grinder (the Comandante and 1Zpresso lines have moved ahead)
Maintenance
The Feldgrind is simple to maintain. Disassemble by unscrewing the catch cup and removing the outer burr. Brush out grounds and coffee oils weekly. The steel burrs don't need special treatment, just keep them dry and free of old grounds.
The burrs will last thousands of hours of home use. Knock doesn't publish a specific lifespan, but based on the burr material and usage patterns of home grinders, you're looking at 5+ years of daily use before any degradation.
If the central shaft develops any play or wobble over time, contact Knock directly. Peter has a reputation for taking care of customers, even if communication can be slow due to the one-person operation.
FAQ
Is the Feldgrind still worth buying?
Yes, if you can find one at a fair price. It remains a capable hand grinder for espresso and filter coffee. However, newer options like the 1Zpresso JX-Pro and Comandante C40 have surpassed it in certain areas, so it's no longer the clear first choice.
How much does a Feldgrind cost?
New from Knock, the Feldgrind retails for about $120-$160 depending on the version and exchange rate (prices are in GBP). Used units sell for $100-$150 on forums and marketplaces.
Can the Feldgrind grind for espresso?
Yes. The 47mm Italmill burrs produce a grind fine enough and consistent enough for espresso. It's not as refined as a $500+ electric espresso grinder, but it's one of the better hand grinders for espresso at its price point.
What's the difference between the Feldgrind and the Feld2?
The Feld2 (also called Feldgrind 2 or Feld2Go) is a revised version with some design improvements. The Feld2 uses a slightly different burr alignment system and catch cup design. Grind performance is similar, with the Feld2 having minor improvements in consistency. If you see either version available, both are good choices.
Wrapping Up
The Feldgrind earned its reputation by doing something no hand grinder at its price had done before: grinding well enough for real espresso. While the competition has heated up since then, the Feldgrind remains a solid choice, especially on the used market. If you want a hand grinder that handles everything from espresso to pour-over in a compact, well-built package, and you can get your hands on one, it won't let you down. Just bring a marker to note your grind settings, because that stepless adjuster doesn't remember for you.
