Shimomura – Chuka Bocho / Chinese Bone Cleaver 185 mm

Brand & Heritage
Founded in 1874 in Sanjo City, one of Japan’s most famous blacksmithing regions, Shimomura has a long legacy of blade-making that began with farming tools like sickles and hoes. Over more than a century, the company has refined its craft, developing knives, scissors, and slicers forged from stainless steel. Shimomura is committed to creating cutting tools that combine sharpness, durability, and ease of care.

Each Shimomura knife goes through about 35 detailed steps, from forging to finishing. Blades are sharpened using the advanced wet grinding method, where water is continuously applied during sharpening. This produces the renowned Hamaguri edge, polished to a mirror-like finish, ensuring smooth cutting performance and superior edge retention compared to ordinary blades.
