This is the Hario 'Skerton' hand grinder. It uses ceramic, conical burrs and can be easily adjusted to produce a range of grind sizes. The rubber base keeps it steady against the table as you grind.
One of the best things about this grinder is the incredible aroma that is trapped in the bottom section, so do take a moment to enjoy it when you unscrew the top before brewing your coffee.
A great portable coffee grinder, a perfect gift for someone getting into coffee and a great all round grinder for any coffee lover.
