Which to buy
Choose the
Skerton Pro if you…
- grind for several cups at once — the glass bowl holds 100 g
- want ceramic burrs — Hario says they shave beans rather than crack them
Choose the
K6 if you…
- want espresso too — KINGrinder lists 40 clicks for it
- want clicks you can count: 60 a turn, 16 microns each
- may drive it with an electric screwdriver — KINGrinder gives the bit and torque in its manual

The same number means different things
Both grinders use a clicks, which makes it tempting to copy a number straight across. Setting 8 clicks sits at grind index 40 on the Skerton Pro but 0 on the K6 — far enough apart to change the cup.
Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

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.

KINGrinder K6
Dialing in the Skerton Pro
The Pro revision fixed the original Skerton's wobble, which was the main source of its inconsistency. Filter and French press are comfortable; espresso is technically reachable and practically frustrating.
Dialing in the K6
KINGrinder's all-rounder, and the value benchmark hand grinders get measured against. External adjustment, 60 clicks a rotation, at 16 microns a click — a coarser step than the 1Zpresso J and X series manage, and the one place you feel the price: espresso is dialable, but in slightly bigger jumps than a stepless grinder gives you. The 48mm stainless heptagonal burrs are what separate it from the rest of the KINGrinder line. If you only ever pull shots, the K4 is the espresso-specific sibling with titanium-coated burrs; the K6 is the one that covers pour over through espresso without being built for either.
