Ohira is a little softer natural stone used to make the traditional kasumi finish that gives the cladding a cloudy, misty look. The stone produces slurry quickly and leaves an even finish on blades from laminated steels, creating visible contrast. It is very simple to use and its advantage is that it leaves very visible traces of previous sharpening on the blade, revealing all irregularities and low spots, in turn telling us which areas of the blade we should hone in on.

Ohira comes from the quarry in the Aichi prefecture in Japan where natural whetstones have been quarried for as long as five generations.

❗ As it is a natural stone that comes directly from a quarry, the stripes and color hues may vary from one stone to another. The stone you receive may differ in color and texture from the stones shown on this page.

🚩 We recommend that you flatten your stone after every use when the stone is already wet and the slurry left on the stone after sharpening will make the process easier. In this way, the stone will be nice, flat and ready for your next sharpening session. After use, store it in a safe, dry and ventilated place, so it can dry naturally, evenly and slowly. The care for and proper storage of your knife will prolong the life of your faithful sharpening tool.

👉 For easier sharpening, we recommend purchasing a Stone Holder (Sink Bridge) to ensure mess-free and a stable position of the stone during sharpening.
