MORIHEI whetstones

Morihei is a long-established whetstone company from Tokyo, whose selection also includes knives and natural stones.

The Morihei Hishiboshi series, better known as MORIHEI Hi, offers a sharpening feel very close to that of a natural stone (JNAT). These stones are partially made from natural stone powder, giving them a very smooth sharpening feedback and excellent responsiveness.

Morihei stones are similar in size to Naniwa and Shapton stones, but slightly thicker (25 mm).

Morihei Hi stones do not require soaking, but I’ve found they work better after soaking for 1–2 minutes. The slurry that forms contains abrasive particles, so the stone should not be wiped clean during sharpening. You can also soak it longer, which softens the surface and improves feedback quality.

To get the best result, it’s recommended to rub open the surface of the stone with a flattening stone after adding water. This ensures effective sharpening from the start. You can also use Morihei’s own Nagura stones for this.

After use, wash the stone and wipe it dry. Let it dry in a well-ventilated area away from direct sunlight and heat sources.

Highlights of Morihei Hi stones:

• Absolutely best for carbon steel knives
• Excellent sharpening feel
• Long-lasting stones

My experience with the Morihei series has grown over time. I must admit that Morihei competes for the title of best stones. The 4000-grit stone, in particular, has become a regular in my workflow and delivers the best results. Based on feedback, these whetstones meet the demands of most serious enthusiasts.
