C40 Nitro Blade®
Built for true coffee enthusiasts and specialty coffee connoisseurs, the C40 (MKIII) Nitro Blade is a robust high performance coffee hand grinder with an advanced burr set design. The selection of the burr material is the proud result of dedicated research and development. Earlier in 2015, a very special high-alloyed, high-nitrogen stainless steel with a new martensitic matrix was chosen as for the line burr material and it was a game changer.
Also comandante redesigned the geometry and structure of the Nitro Blade burr to get the grind performance they were looking for and the particle distribution which worked best with brewing fresh ground specialty arabica beans. Manufacturing a Nitro Blade is a serious engineering task which requires special tools and machinery, excellent craftsmanship and lots of experience. High-nitrogen martensitic steel is extremely difficult to work with. But when nished, it is tough, highly wear resistant and has a high degree of edge retention.
After hardening and tempering a nished Nitro Blade, a last engineering kick was given: Tiny micro-blades on the tips of the Z-teeth was added to give it an ultra-sharp burr entry. The grind result gives a very refined particle size distribution for all grind grades from coarse grind for hand brewing to fine grind for pulling espresso shots.
Stainless steel is the right choice to build a robust coffee grinder. So the C40 has a stainless steel body, a stainless steel axle, a stainless steel crank and stainless steel micro ball bearings.
The “naked” C40 has a brushed stainless steel body. For the wood version, a genuine wood layer laminated on top of the stainless steel body. Both body surfaces give you a solid grip for serious crank action.
Comandante burr sets are always cut from solid metal blocks by experienced craftsmen. Burr geometry has been optimized to achieve excellent grind thruput with medium crank torque delivering refined grind particle size distribution for best brew results. Grind thruput averages at 1 coffee bean per turn at a comfortable medium turning force.
Nitro Blade Burr Set
The Nitro Blade burr set is the ultimate performance choice. It “cuts” coffee beans in a very unique way. The grind result is extremely exact and very uniform with the least amount of coffee dust. Both ring and core are cut out of a solid block of high-alloyed, high-nitrogen stainless steel. This makes the Nitro Blade very sharp and strong with excellent edge retention and wear resistance. Nitro Blade is also extra non-corrosive and shows an excellent cut performance.
Highly Inert Burr Surface
The Nitro Blade‘s steel surface is highly inert and therefore performs with absolute sensoric neutrality. This is particularly essential when grinding complex acidic high quality micro lot arabica coffee. The Nitro Blade with its physical and chemical properties is the top choice for all serious coffe brewers and top baristas. Stainless steel grinder core geometry “cuts” through the beans and delivers a much better grind result with much less undesired coffee dust. Ceramic burrs work with more push & squeeze action and as a result are less consistent. On the other hand steel itself “takes away” fine fruity notes and acidity fo the specialty coffees you intend to use.
Try your Nitro Blade also with salt and pepper or other dry herbs. You will be surprised about the grind result. Fresh ground seasoned salt powder – extremely tasty!
Axle With Micro Ball Bearings
The center axle is fixed and supported by two micro ball bearings for better distribution of force and grind momentum. Both micro ball bearings are encapsulated with rubber for protection and smooth operation.
The turning crank is made of stainless steel and can be removed to better fill the C40. The clear disc on the crank has been pressed onto the stainless steel quite solidly, but can be adjusted if necessary.
100% Natural Oak Wood
The wooden knob is made in the Black Forest region. It is made of 100% natural oak wood and is mounted with a push-button-mechanism onto the crank. You are able to remove it and click it back on. Shape and form of the wooden knob have been designed for comfortable and solid feel during grinding.
All wooden surfaces have been treated with a safe Wax-Oil.
Safe TRITANTM (BPA Free)
All burr frame parts in synthetic material are made with BPA-free copolyester TRITANTM which is known to be a very robust and break-resistant synthetic material. According to Eastman, TRITANTM is not only BPA-free, but it is also not manufactured with bisphenol-S or any other bisphenol compounds. In addition, third-party labs have tested TRITANTM and the results have demonstrated that it is free of estrogenic and androgenic activity. A very safe material to hold your precious coffee beans.
Grind Grade Selection – 3-Way Click Action
The grind grade selection dial has been designed like a three-legged star with a proper click action. Three independent micro steel ball click units are used to assure a balanced pressure scenario for the burr conus. It is located at the bottom of the C40. Use three fingertips and turn the star clock-wise to get a finer grind result or counter- clock-wise for a coarser grind. The click action firmly locks in your preferred grind grade.
And yes it fits on Aeropress just like Porlex does.
Glass Jar With Lid
The glass jar at the bottom holds 40 grams of coffee which gives you approximately 4 – 5 cups of coffee. Glass is a perfect storage device and you can easily clean it with hot water. You get 2 glass jars with the C40. One in clear and one in brown. Plus, you get a lid for your extra glass jar. The lid is made of Urochem 371, which is manufactured from renewable natural resources and can be recycled.
Please Be Careful!
Please be extra careful when you use this coffee grinder. The attached glass container may break when it hits a hard surface like the floor. Broken glass is dangerous and can seriously harm you!
Please don‘t let children play with this coffee grinder. It is heavy, it has very sharp blades and a glass jar which can break!
Also please be careful with your fingers when you operate close to the burr edges. The Burr edges of Nitro Blade are extra sharp. You can easily cut and harm yourself if you are not careful.
