Sadao Nishihara is a renowned knife handle maker in Japan. His wood handles, using finest quality ironwood, birch wood or cherry wood, have known to be one of the most ergonomic and beautifully crafted knife handles in Japan.

Wash and dry with a soft sponge, and safely store after use. Avoid cutting into bones, frozen foods, hard fruit pits.

Cutting Surface:

Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.


We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.
