Thread: Using oil with coticule questions

If it did penetrate you would struggle to use water on it in the future. As the water would bead off. And it might have a long term effect on the glue of a backed coticule. You may also find the hone looses it's abrasive power under slurries making it a finishing or near finishing stone without the ability to reset a bevel. For a razor only stone this isn't going to be a problem but if you wanted to use it for knives as well you may have slowed it to the point of been useless.

It's your stone so do what you want with it. I personally wouldn't use oil unless I had to, but then I do a 1 stone method when the coticule comes out.

I would also never buy a coti that I knew had been used with oil, Because I don't like anything oily getting near my synthetics.
