Comandante - C40 MK4 Lab Series Nitro Blade Hand Grinder - Stone Washed
Comandante C40 MK4 Nitro Blade is a new edition of the iconic coffee grinder, considered by many to be the best hand grinder in the world.
Every Comandante® C40 grinder is meticulously crafted by a team of experts and built to last, made from carefully selected materials. Its iconic shape has become synonymous with quality and world-class grinding performance — a timeless, clean design created in the name of flavor clarity.
Begin with the burr
Burrs are usually treated as commodity items — functional and standardized. Hidden inside the grinder, they are rarely appreciated and even more rarely questioned. But what if burr geometry holds the key to unlocking hidden flavor potential — something that roast curves or brew methods cannot fully reveal?
For over a decade, Comandante® founder Bernd Braune has been developing innovative concepts for conical burr sets. At the Bavarian Burr Lab, engineers push the boundaries of machining technology and design pioneering tooling to bring these ideas to life.
The Lab Series gives you greater freedom to experiment and explore flavor possibilities. Global brewing styles and taste preferences are subjective and — just like coffee itself — wonderfully diverse. Embrace this diversity, boldly explore what tastes best to you, and enjoy not only the result, but also the journey that leads you there.
Nitro Blade® Burr
"Back in 2005, I started my small specialty coffee roastery – drawn in by the incredible flavors and outstanding cup qualities that specialty coffee had to offer. Those early years were filled with roasting, cupping, and traveling to connect directly with producers at origin.
Roasting and brewing in the field was manageable. But precise grinding – the key to truly tasting and deciding on a coffee – was the real challenge.
None of the hand grinders I tried gave me the clarity or consistency needed. I kept dreaming of EK43-level performance in a compact format I could carry deep into the mountains. I just needed a grind I could trust.
Most conical burrs at the time were designed for electric grinders. Nobody had really considered what a manually operated precision burr would require: superb grind quality, smooth torque, comfortable ergonomics, clean particle distribution – and ultimately, absolute taste clarity.
Then came Cup of Excellence. It shifted the coffee world’s focus toward extraordinary cup quality and flavor expression.
The bar was rising. This new era of specialty coffee needed a grinder with a true specialty burr to match.
So I started building one. And after years of prototyping, testing, and investing in serious lab equipment, it finally came together. In 2015, I launched my first Nitro Blade® based hand grinder: the Comandante® C40 Mk3. I handed a few early prototypes to friends – who soon went on to win major brew competitions. Nitro Blade® quickly earned its reputation as the Original Game Changer.
Ten years later, Nitro Blade® is still the gold standard. Built to last, engineered for clarity, and trusted by champions and home brewers alike.
I’m so glad you’ve got one in your hands now. Welcome to the journey, and to a community that truly loves great coffee and fine craftsmanship. Enjoy every cup!"

Nitro Rex® – steel like no other
Nitro Rex® is more than stainless steel — it is an achievement of material engineering and craftsmanship. It contains over 17% chromium and precisely balanced amounts of vanadium, molybdenum, and other valuable micro-alloys, giving it outstanding corrosion resistance, hardness, and wear resistance. Its complex remelting process creates a fine, homogeneous structure and a silver-white surface that is not only aesthetically striking but also eliminates the need for coatings. Nitro Rex® stays exactly as it is made: robust, durable, and completely flavor-neutral — allowing coffee to retain its full character.
Nitro Rex® forms the heart of the grinders. It ensures consistent precision and durability, appreciated worldwide — whether grinding ultra-fine espresso or coarse filter coffee. Every COMANDANTE grinder is created for people who refuse to compromise and who share a passion for quality, craftsmanship, and perfect coffee.
QTP® – high-performance techno-polymer
Not all plastics are the same. At Comandante®, advanced materials are chosen with purpose. QTP® is a high-performance techno-polymer — a long-chain polymer matrix reinforced with quartz nanoparticles. It looks and feels like ceramic, yet offers the strength of a super-composite. Designed for durability and precision, it is also food-safe and water-resistant. Quietly cutting-edge, built to perform.
Scope of Delivery

1 × Crank with black-lacquered oak knob*
1 × Transparent polymer Bean Jar
1 × Dark glass Bean Jar with lid**
1 × Comandante® wristband, small
