Made using waste material from the manufacture of other stones, the "American Mutt" series is a unique extra-extra-coarse hybrid ceramic made of a blend of aluminum oxide, silicon carbide, and a small amount of diamond in mixed grits. These stones hog off steel so rapidly that you'll quickly develop a thick "mud" of metal swarf on the stone! However, the inclusion of mixed finer grits causes it to leave a finer finish than one would expect for so aggressive a stone. Perfect for re profiling, bevel-setting, and repairing damaged edges, especially in locations where power sources for grinders or other electric stock removal are unavailable. Will not blunt like a file if used on dirty surfaces. Economical and high-performance, these stones are sure to please! For best results, fully saturate in water before use and use with heavy pressure.
