Converting a setting

The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.
1Zpresso K-Max
Kinu M47 Classic
Dialing in the K-Max
A larger burr set than the J series and correspondingly faster, aimed squarely at espresso with enough range to reach filter. Its click resolution near the fine end is the reason to own it.
Dialing in the M47 Classic
A heavy, precision-built hand grinder with stepless adjustment and genuine espresso capability. The lack of detents means repeatability depends on your own reference marks — the settings here are targets rather than clicks.
