This remarkable hand-powered grinder is made by Hario and features ultra-sharp ceramic conical burrs. The burrs are adjustable and lock into place when you've found that sweet spot, grind-wise. There is no motor; it is fully powered by elbow grease. But the quality of the grind is unsurpassed by electric grinders that cost ten times as much. A compact grinder for travel, and wonderful for making a quiet cup of coffee at home.
