Humor aside, though that previous post was no joke, when I used to hone a lot more than I do now I used Eschers quite a bit. Still have one I'm hanging on to. Sham told me years ago that honing a razor that isn't already shave ready is a waste of good stone on an Escher. Get it up to speed on your stone of choice and then finish on your Escher.

I've done it like the label says, with a thin slurry and dilute to water only, and I've done it water only. Gary Haywood bought a yellow green from me. A Barber's Delight. He was mostly a coticule honer at that time and said he thought the edges were 'too crisp' compared with the coticule edge. I know what he meant. Still, IME an Escher finished edge is not as 'crisp' as a synthetic finished edge. So it might depend on what the end user is expecting out of the hone. IMHO.
