Comandante Coffee Grinder C40 MK4 Nitro Blade The Comandante Coffee Grinder C40 Nitro Blade coffee grinders impress with their unique and beautiful design and are manufactured 100% in Unteraching, Germany. Highest quality through high-class handling and robust materials! You can grind from powder-fine (Mokka) to very coarse (Karlsbader pot) with an easy click-system up to 35 different grinding levels. The grinding mechanism 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. 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. 100% Made in Germany represents the usage of stainless steel for all metal parts, glass for the jar, BPA-free TRITAN plastic for the engine frame, and real wood for coating and knob. Comandante hand grinders were designed and built to last a lifetime. Convince yourself.
