These slip stones are made to our design and to a specified hardness to best combine cutting speed and durability.
Widely used for sharpening firmer gouges; scribing gouges; carving tools and radiused blades; these stones can be used on nearly any curved cutting edge of simple or compound shape.
The 8000x is for final touch-up or occasional stropping while carving.
Also available in 1000x and 4000x.
