The ceramic burrs of the Hario Coffee Mill OCTO won't damage your coffee beans with heat caused by friction as you grind them. The mill has an octagonal hourglass shape that is easy to grip.

The ground size adjustment knob is marked with "Coarse" and "Fine" so you can see the right direction at a glance.
