Application examples - Sharpening stone for sculptors

Almost all chisels can be sharpened with these stones. Use the large concave stone for the outer sides and the small convex stone for the inner sides. In the image at the top left, you can see how a chisel is moved on the stone. It is not only moved back and forth but also sideways at the same time. This has the advantage that you can work on much larger chisels than the concave groove suggests.

Since Japanese stones are soft, you can change the shape of the stone as needed with waterproof sandpaper (K 80 - 120). This can be useful with the convex stone if, for example, you want to hollow out a Gaißfuß from the inside but do not find the right shape on the stone. Wet waterproof sandpaper on a flat board and pull the stone over it several times - you will have the desired shape.

If you want to adjust the concave groove for a frequently used chisel: Take a round piece of wood that roughly corresponds to the radius of the chisel, wrap the waterproof sandpaper around it, and enlarge the groove with it.

Lastly: You can also use the flat back of the concave stones for chisels.
