Don't be afraid of using the arkie with oil. Just wash it immediately afterwards. I only use mineral oil though. Maybe others present a problem but I don't know.Interesting, all the different results, water vs soapy water vs oil. I have a black translucent I am still working with steel. My intention was to use it as a finishing hone. I was thinking of trying to use water because once oil is used it is harder to come back to water. What to do? I guess I could try water >soapy water>oil (last resort).
