Gyokucho Natural Waterstone A (Wider)

Dimensions: Approximately 6.5 × 3 × 0.875 inches.

Its broader surface area makes it particularly suitable for wider blades and plane irons.

The key to using a natural whetstone is to put just a little bit of water on the surface. To avoid cracking the stone, never soak natural stones in water.

Start sliding the blade back and forth, and the water will quickly turn black. Don’t wash away this black water, as it helps polish your blade.

Since it is a super fine finishing stone, you will not hear the regular scraping sound you hear when using artificial stones. There is almost no sound when you sharpen the blade with a natural whetstone.
