The Yoshimune Difference

Aogami Super is one of the most prized high-carbon steels in Japanese knife-making - a molybdenum and vanadium-enriched alloy that achieves exceptional hardness (64 HRC) and outstanding edge retention. The stainless cladding protects the reactive carbon core from rust on the blade flats, while the Aogami Super edge delivers the sharpness and retention that carbon steel is known for. The black hammered finish adds a bold, dramatic aesthetic while creating small air pockets between blade and food, reducing drag and preventing thin slices from sticking. At 240mm with a 1.8mm spine, this is a long, thin, laser-like blade suited to breaking down larger proteins, slicing, and sustained prep work. The walnut octagonal handle provides a secure, comfortable grip.

Care and Maintenance

• Hand wash only - never dishwasher
• Dry immediately after use - the exposed Aogami Super edge will rust if left wet
• Apply a light coat of food-safe oil to the edge if storing for extended periods
• 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
