Awesome information, as I stated before, where else in the world will a person get this type and wealth of information than on this site, man this is great, I rest assured that my question is answered. No such thing as a brown Thuringian but another type of unique type of stone I have never heard of, I will keep honing and learning. Thank you very much everybody for you input, I have again learned more and gained more knowledge on the art of honing and hone types. Keep on trucking, Rudy!
