Honestly, we're always skeptical about manual hand grinders, so we have to test it to convince ourselves before we put it up for sale. It's suprsingly does the job better than what we expected. We're able to adjust the right grind size from paper filter to french press. The long handle make it easier to grind. For 12g, it take about 30 to 45 seconds.
What we didn't like very much about it is the weight. Cafede Kona constructed this grinder using cast iron, instead of stainless steel or ceremic. But we bet it will be super durable.
Capacity: grinding compartment can take 25g, but the ground holder can hold much more.
Materials: Cast iron and wood
2 color choice, light and dark wood
