?ALTSTONE: Precision-engineered in Japan
In Japan, sharpening blades has never been just the work of professionals. For many years, people have used whetstones at home to keep their kitchen knives sharp?it’s a tradition deeply rooted in daily life.

This culture has shaped the evolution of Japanese whetstones themselves. Brands like Shapton, King, Naniwa, and Suehiro have each developed their own technologies and philosophies, refining bonding methods, abrasive design, and sharpening feel.

Japan has developed a particularly rich and refined sharpening culture. Few other countries offer such a wide variety of products tailored to different blade types, with such careful attention to sharpening feel and finish. In terms of materials, structure, and craftsmanship, Japanese sharpening stones continue to set a high standard globally.

ALTSTONE offers products that reflect the refinement and subtlety of Japan’s sharpening culture. For example, our FUKAMI series is designed to handle a wide variety of blades?from stainless steel kitchen knives and carbon steel blades to blades with curved edges, like kitchen knives, and compact utility knives.

By carefully selecting specifications such as hardness and surface texture, we aim to ensure a smooth and satisfying sharpening experience. Whether you’re just starting out or already familiar with sharpening, we focus on offering stones that are easy to use?yet precise enough that you can clearly feel the difference in sharpness after each session.

Sharpening may not be flashy. But there’s something quietly special about the meal you prepare with a freshly sharpened blade. We hope that an ALTSTONE whetstone can be part of that small but meaningful change in your everyday cooking.
