The Hard Black (Ultra Fine) is the finest grade Novaculite stone (together with Translucent) available today. It is considered a surgical grade stone and was originally only used for industrial applications where an extremely fine polish was required. The Hard Black is a finishing/polishing stone and is a perfect complement and follow-on stone from the Soft Arkansas. This stone will produce an edge of immaculate polish and finish and is requested by demanding woodworkers everywhere. This particular pocket stone measures 4" long, 1" wide and 7/16" thick. It is an excellent choice for touch-up tasks and for sharpening small knives. The stone comes with a leather pouch for clean storage and protection.
Our Natural Arkansas Stones
All our Natural Arkansas Stones (Soft, Hard Black and Hard Translucent) are hand-crafted from Novaculite, a naturally occurring stone quarried from rock formations in the state of Arkansas. Traditionally, when our forebears referred to Arkansas Stones they referred to Novaculite stones. Unfortunately, in recent years some vendors have begun to refer to their stones as Arkansas Stones when in fact they are not Natural Novaculite Stones but rather are made from material with lesser sharpening and abrasive qualities such as reconstituted stones or sand stones. So, to make sure you are getting the real thing remember to ask what exactly make up that particular "Arkansas" Stone.
