DMT’s® revolutionary DuoSharp™ design offers considerable cost savings as well as the convenience of a two-sided diamond precision stone. Simply turn the stone over to change grits. In effect you get one side for free!

Also available for greater ease of use - the DMT-B8250 DuoBase provides a secure, non-slipping hold for 8" or 10" DuoSharp whetstones (see photo below).
