Thread: Determining hone grit rating

Ok, I've found a vintage combination hone from China (picture below). The problem is the seller says that he doesn't know the rating on it because rating print has been worn off the hone. Just wondering how hard it would to be determine what it is and if I should purchase it or stay far far away from it.

For razors I would pass. Aluminum oxide combo hones are generally too coarse IMO.

thanks man that's all I needed to know.
