This grinder is small and sturdy. Its compact size and metal body makes it ideal for taking with you on a trip. It also features a non-slip bottom that will help you stabilise the grinder during use.All of the manual coffee grinders produced by Hario use burrs made of ceramic: conical ceramic burrs transfer less heat and shave coffee beans instead of cracking them like blade grinders often do. This process also results in a more consistent grind that can be easily adjusted and set for repeat use.
