Hello, has anyone used this hone? its an Imperia La Roccia 12-15k finishing hone. It is sold on the bay from powertoosnow. I bought the small one, its advertised as a natural stone its light gray in color. Tried it on an old french razor that always took a while to hone. Went a few circles and passes stropped and it shaved very well. As I use it more I will let you know how it does. Comes lapped and with a slurry stone. Let me know what you think. Thanks.
