Give the Smith’s a try on the Coticule and do more laps with just water, Smith’s and light pressure even strokes at the end. 2-3 drops on a wet stone, it’s about 6 bucks at Ace or Lowes.

Recently I gave this advice to another member who was disappointed with his Coticule, he was amazed with the results. He was so stoked on the stuff, I think he’s drinking it now.

I suspect the oil lifts the edge a bit, so it only touches the tips of the grit on the stone and there by polishes the edge. It works great on Coticules and Thüringen stones & is water soluble so it does not damage the stone, washes off.
Just curious. Why do you need to go to all this trouble if the stone is actually a fine grit finisher ?
