Sharpening & dressing · review
A wet wheel running through water, which is the only way to sharpen a thin edge without risking the temper.
Where we come out The only machine here that cannot ruin a chisel, and the one whose tank you must remember to empty.
A hundred and twenty-two euros for two stations on one base: a 200 mm (7.87 in) wheel running through water and a 150 mm (5.91 in) dry wheel.
A dry wheel at 2,980 rpm puts heat into a thin edge faster than the steel can shed it. Above roughly 200 °C (392 °F), hardened tool steel begins to soften — and the visible sign, a straw or blue tint at the very tip, means that part of the tool is now unhardened and will not hold an edge. The only remedy is to grind it away and start again.
A wheel turning through a water bath cannot get there. You can sharpen a chisel, a plane iron, a turning gouge or a kitchen knife with the tool in constant contact and no anxiety at all. It is slower than dry grinding, which is exactly why it is safe.
Rough work — reshaping a bevel, taking a nick out — belongs on the 150 mm (5.91 in) dry wheel, quickly and with dips in water. The wet wheel then takes it to an edge.
Empty the tank after use. A wheel left standing in water soaks it up on the submerged side, becomes heavier and softer there, and runs out of balance from then on. Drain it, spin it dry for a moment, and it will stay true.

Hardened tool steel loses its hardness when it gets hot — from around 200 °C (392 °F) the structure changes and the edge becomes soft. On a thin edge that happens in seconds on a dry wheel, and the tell-tale is a straw or blue color on the very tip. Once it has happened, grinding back past the discoloured metal is the only fix. A wheel running through water cannot reach that temperature.
Yes, every time. A wheel left standing in water absorbs it on the submerged side, which makes that side heavier and softer — the wheel then runs out of balance and wears unevenly. Drain the tank when you finish, and let the wheel spin dry for a moment before you put the guard back.
