Ceramic stones are valued for their durability and the very keen edge they give in the finer grits. These two stones are ideal for carvers who do all their sharpening free hand and can quickly wear grooves in water stones.
A. The dark stone is about 800 grit. It is used for edge shaping.
B. The white stone is about 8000 grit and is used for final honing.
Both are 4" x 2" x 1/2". The manufacturer states that neither requires lubrication and that both clean up quickly with soap and water. It is our belief that they benefit from a bit of water during use (preferably with a drop of soap in it) to avoid any grain plugging. An ounce of prevention....
Both come with vinyl slip covers. Good toolbox stones.
