I am now the proud owner of a thuringian hone. I don't believe it's an escher, but it's damn smooth.

I lapped the chips out of it (up to 2000 grit) and chamfered it, and I gave my razor a few x-pattern swipes on it as I would have with a barber's hone, but I didn't want to do much more to it until I found more information.

It's 1"x5"x1/2" and is in a wooden box (but removeable, the glue has given out).

How should I go about using it properly? Is it merely a finishing hone, or can I use it weekly as I would with a barber's hone to touch up my edge?

It's quite hard, and it take a moderate amount of work to produce a slurry. The slurry is greyish white and translucent with an earthy smell. It's also butter smooth, no surface abnormalities outside of one spot of slight discoloration.

Any info on how to use it?
