Ohira Tomae High-Quality Natural Stone

This Ohira Tomae is one of the most popular natural finishing stones on our site, prized for its balance of cutting speed, feel, and final finish. We source these stones directly from Imanishi Stone Company, where each piece is personally evaluated and graded by Mr. Imanishi before receiving his stamp. Stones like this are no longer being mined, making well-preserved examples increasingly difficult to find.

This is a fine finishing stone with an approximate grit rating in the 8–10K range. It has a firm, hard feel, cuts faster than many stones in its class, and leaves a clean, refined finish suitable for high-end kitchen knives. The stone is notably thick and will provide many years of service. Mr. Imanishi grades this example as High Quality; it was mined in the early 1970s and stored in his basement until release. We photograph and weigh each stone individually as it sells, so the stone shown is the exact one you will receive.

Care Instructions: This natural stone is very easy to care for and does not require sealing. Simply wet the surface before use, sharpen as normal, and allow the stone to air dry naturally when finished. Do not perma-soak the stone. Store it indoors in a temperature-controlled environment—never in an unheated garage or shed. If moisture inside the stone freezes, expansion can cause cracking or permanent damage.
