Shapton Naoru Cast Iron Lapping System – Preowned, Unused

A flat sharpening stone is essential for consistent honing, particularly when working with straight razors. The Shapton Naoru Cast Iron Lapping System provides a substantial, durable platform for flattening and resurfacing waterstones, helping keep your honing setup performing at its best.

The Naoru combines a cast iron plate with loose abrasive powder and water to restore an even working surface. Its distinctive geometric grooves help distribute the abrasive slurry across the plate, supporting efficient material removal and controlled flattening. Changing the lapping powder allows the surface finish to be tailored to the stone being maintained.

This example is preowned but unused, offering an opportunity to add a quality Japanese stone maintenance tool to your collection at a reduced price.
