The benchmark among professional hand grinders for coffee. The grinding mechanism of the C40 Nitro Blade grinder is entirely made of carbon steel and manufactured using a patented process. Producing a carbon steel blade is a challenging task that requires specialized tools and machines, excellent craftsmanship, and extensive experience. Carbon steel is extremely difficult to work with. However, once completed, it is hard, highly abrasion-resistant, and has excellent edge stability. The Comandante development team focuses on material expertise and attention to detail. The result is a hand grinder "made in Germany" that impresses with finely tuned technology. The edges of the grinding discs are sharpened again after hardening, allowing them to "cut" the coffee beans. Thanks to the unique grinding technology, the grinder produces an extremely precise and homogeneous grinding result with virtually no "fines" across all grind settings. The power transfer during grinding is optimal, and a double ball bearing makes the cranking smooth. Here, too, it is evident that professionals are at work.
