🪨 About the Ohira mine

Ohira mine - One of the most famous natural sharpening stone mining sites in Japan. It is located in the hills of Kyoto Prefecture, close to the Hōzukawa and Atago mountain ranges, where the highest quality stone has been mined since the Edo period (17th century) Awasedo stones.

The geology of the region - extremely fine sedimentary layers of quartzite, silica and iron oxides - has resulted in some of the cleanest, most homogeneous and highest quality stone in Japan. Ohira is particularly famous for its Shiro Suita, Asagi, Thomas stones that are appreciated by both professional Japanese knife sharpeners and shaving knife masters.

Some areas of the Ohira mine are currently closed, so good old specimens are highly prized by collectors and professionals.

🎯 Recommended use:

• For professional knife sharpeners
• For the maintenance of razors and clippers
• For collectors looking for premium Japanese natural finishing stone
• For kitchen knives requiring a sharp, but delicately coarse microdot-free cut
