Nitro Blades Nitro Blade burrs are made out of a very special stainless steel alloy which contains iron, chromium, molybdenum, vanadium, manganese, silicon, a little carbon, and nitrogen. The benefits include superior teeth sharpness, greater edge holding capability, and an electro-chemical neutral surface property. Grinding with this type of burr set gives you an enhanced particle generation and particle distribution. You will also achieve a decrease in grind process oxidation, which is very important when you grind highly acidic light roast Arabica beans. A burr set built with this steel is able to grind salt as fine as baby powder, with no oxidation damage to the metal. Most steel burr sets which are used in other hand grinders on the market are burrs originally designed for electric espresso machines. The objective of those old burr designs was to quickly get a grind job done by a little electric engine for a shot of Italian-style coffee. An optimized particle distribution for a filter-style coffee was not even on the agenda for those burr sets. Our burr design was developed for a modern hand grinder, with an advanced grind performance, and an elevated cupping experience in mind.. The ergonomics and physical experience using a hand grinder with a Nitro Blade burr set is very pleasing. The bean throughput per turn at a moderate torque value is 1. That means that with every turn, one bean is processed. This is a very productive rate, with a moderate torque rate of 2.8 Newton meter not difficult to achieve.
