I just got the KME system, and have a question about oil and water. Unless I am misreading things, they recommend using the stones with the oil that is included with the stone. I guess that means putting a few drops of oil on the stone and rubbing it around before sharpening with it? Then they recommend washing the stones off with soap and water, to clean the metal shavings off the stone, I guess? How does that work, using oil for cutting and soap and water for cleaning? I thought you used oil to clean an oil stone, and soap and water to clean a water stone. Is this incorrect?
