German manual coffee grinder, made in 1910, has a square body, a drawer below to collect powdered coffee, and a horizontal flat twist handle with a round knob. The upper funnel holds up to 200 grams of coffee roasted beans.
The coffee grinder needs to grind quickly, not to take too much time. During the grinding process, if the quality of the grinder is not good, the coffee beans will be hot causing a loss of smell, and affecting taste of the final cup of coffee.
