Niwaki's sharpening stones are designed for secateurs, but are also great for shears, clippers and other blades. The concave edge follows the curve of the blade perfectly, and they’re small enough to get into tight spots.
The #220 is a course stone, for rough blades.
See use instructions below, but the golden rule is to soak thoroughly each time before use. And not to drop them.
