I found a "Apart" hone it is one of those reddish hones with the name stamped into one surface. The hone was quite misused. I tried cleaning it with a nagura stone witch it made quite messy. So I lapped it on a diamond plate using soap and water as a slurry. The hone feels very smooth, has a very fine grain when viewed with 30x.

Water beads up on the surface.:

Does anyone know about these stones?
Is this normal or could the stone be impregnated with oil?
If the stone is impregnated with oil is it ok to use?
