Thread: Mystery water hone- need ID help

So I just acquired this "Finest Grit Water Hone" that states on the package "The only razor hone produced in America". Now I don't know about you, but everything about this hone says Thuringian to me. The size, appearance, directions on the box and description of the hone, etc. I also is fairly soft, scratches easily and leaves a white mark, slurries, feels like and even smells like other Thuris I have. It is a dark gray with strong olive tint. What do you think? Is the "Produced in America part" creative marketing, or could this be some other sort of stone?
