A sharpening stone is only as good as its surface. Over time, even high quality whetstones develop a concave hollow from repeated use — and a dished stone produces a convex edge rather than the flat bevel needed for a true shave-ready finish. The Shapton Diamond Lapping Plate restores Shapton stones to perfect flatness, accurate to within 5 microns, ensuring consistent abrasive contact across the full blade width with every pass. Regular lapping also extends stone life by maintaining an even wear pattern. Compatible with the full Shapton range — both Professional Series and Glass Stones.

How to Use: Place the lapping plate on a flat, stable surface. Add water and flatten the stone with circular or figure-eight motions until the surface is uniformly flat. Rinse both surfaces after use.
