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 4000x is the most useful combination of cutting speed; hardness; and degree of finish obtained. It cuts quickly; but still leaves a tool with a near-mirror finish superior to that achieved with a hard Arkansas slip.
Also available in 1000x and 8000x.
