ARKANSAS stone is a natural oilstone, extracted from the Ozark Mountains, a mountain range in the United States of America going from Red River in Oklahoma to the confluence of Missouri and Mississippi. There is no other natural or artificial stone so suitable for the sharpening of particularly well sharpened and delicate cutting edges like those of the chirurgical tools, the engraver’s, jeweller’s, sculptor’s tools, etc. ARKANSAS stone’s grain is finer than the grain of any other oilstone. Thanks to their hardness, the stones are not damaged by the tools. ARKANSAS stone, a first quality product, is always the most economical.
