Naniwa Sharpening Stone Fixer

To get the most from your sharpening stone, it needs to be perfectly flat. Over time and after sharpening sessions, a stone can wear and form a concave shape which lowers its effectiveness.

With the stone fixer, you can flatten your stone and easily bring it back to its most efficient state.

To use, simply soak both the stone fixer and the whetstone you are repairing in water for a couple of minutes until no bubbles appear from either and slowly work the stone fixer over the length of your stone.

This stone is not for sharpening your knives.
