The Yoshimune Difference

Aogami #2 (Blue Steel #2 by Hitachi Metals) is a chromium and tungsten-enriched high-carbon steel that delivers excellent edge sharpness with slightly superior edge retention compared to White Steel #2 - a favourite among Japanese knife enthusiasts for its balance of performance and sharpenability. The gyuto is the Japanese interpretation of the Western chef's knife - a versatile multipurpose blade capable of push cuts, pull cuts, and rock chopping across meat, fish, vegetables, and fruit. At 270mm, this is a professional-length blade that excels at breaking down larger proteins, long slicing strokes, and sustained prep work. The kurouchi finish is left intact on the blade flats, giving the knife a rugged, honest character and offering slightly better rust resistance than a fully polished carbon blade. The walnut handle with resin ferrule provides a secure, comfortable grip.

Care and Maintenance

• Hand wash only - never dishwasher
• Dry immediately after use - Aogami #2 will rust if left wet
• Apply a light coat of food-safe oil if storing for extended periods
• Expect a natural patina to develop with use - this is normal and protective
• Do not cut frozen food or bones - the edge will chip
• Sharpen with a whetstone to maintain the edge
• Store on a magnetic strip or in a knife block
