A set of 4 natural Arkansas sharpening stones (oil stones) by Two Cherries (Kirschen), designed specifically for sharpening and honing the complex shapes of carving tools like gouges, V-tools, and other specialized blades. The stones feature different profiles/shapes to access and polish the inner curves and edges of the tools. They are a very fine natural stone, comparable to a high grit of 6000/8000, and are intended for use with sharpening oil.
