It is a fine-grained and soft stone that is known for its ability to achieve a high gloss and fine edge. Hazuya is a natural stone that is mined in various locations in Japan. Its texture is usually fine and fine-grained, which allows for precision knife sharpening. Hazuya is traditionally used as a stone for the final finishing touch to sharpening, following a coarser grind on a coarser stone.
When using Hazuya stone, it is important to practice proper sharpening technique. The stone is soaked in water and then used in combination with light pressure and circular motions when sharpening the knife.
