Its a form of Barbers Hone. And those were usually advertised as "Hone dry, or with lather"
If somebody else has a Lipshaw hone that includes the instructions, and can say otherwise, please chime in!
You are the one saying its possilbly made of the same material as a #118.
Do you have a box or instructions with the hone you are trying to de-grease?
How & why have you indentify the hone in the picture as a Lipshaw Hone?
