Nakiyo Extra Large Professional Finishing Stone

If you want your knives sharp enough to shave, our finishing stones are for you. Offered in three ultra-high grits for extreme polishing, they should be used in tandem with lower-grit sharpening stones that do most of the work.

Synthetic corundum waterstones are the tool of choice for most skilled sharpeners, and for good reason. Offering faster action than diamond stones without damaging your knives like pull-through and automatic sharpeners, these stones produce a finer finish than nearly any other method.

Nakiyo waterstones are made of solid bonded corundum and feature a much larger surface area—over 22 square inches—than other stones on the market in order to improve durability and ease of use. A non-slip rubber base is included with each stone.

Tips & Care

Nakiyo waterstones must be soaked in water for at least 15 minutes before use and kept wet during use by periodically dripping or spraying water onto the surface. They should not be submerged for long-term storage.

Be sure to sharpen your knife at its correct edge angle. This will typically be 15-18° for Japanese knives and 20-25° for Western knives.

Your stone will last for many years of regular use and care, but over time, it will preferentially wear in areas where you apply the most pressure. The surface can be easily flattened with a flattening stone to restore it to maximum effectiveness.
