An upgraded version of K-Max with a foldable handle and a different design. The finer adjustment mechanism lets you dial into the preferred grind size for all brewing methods more easily. This grinder is designed for complexity in your cup, and is suitable for pour over, filter, aeropress, french press - it can also be used for espresso as well!
More Precise: The adjustment mechanism of K-Ultra is finer than the K-Series grinders. There are 10 numbers/100 clicks in one rotation, and the burr moves by 20 microns per click.
More Compact: With the classical external adjustment mechanism of K-Series, K-Ultra has the latest foldable handle that makes the grinder more compact and portable.
Optimized design: K-Ultra features a rounded body with curved edges, making it feel more comfortable in the hand.
