Suihei-kun #100 Flattening Stone

This is a full benchstone sized very aggressive 100 grit ceramic flattening stone with grooves. Great for flattening hard ceramic stones, as well as softer 'muddy' stones. Fine stones (3000 grit plus) should be smoothed over with a nagura after using this stone. The deep grooves made by the coarse 100 grit in the flattener will reduce the efficiency of the finer grit stones if they are not smoothed away. Soak flattener and stone to be flattened before use. Not recommended for natural stones. 

This flattener is used in our shop for flattening stones under 500 grit as those extra coarse stones can damage diamond flatteners by wearing off the nickel plating holding the diamonds.
