Arkansas Diamond Files (USA) - DF-744

• Genuine natural hard Arkansas oilstone is the rarest and is accepted as the finest abrasive stone in existance. 
• Ultra Hard Arkansas bench stones are extremely dense and will enable a user to polish an already sharpened edge to a finish beyond what other stones would yield. 
• Hard Arkansas stone is the pure form of Novaculite rock and as such is found only in small deposits in the OUACHITA Mountains area surrounding Hot Springs.
