Heritage & Use

The Masamoto Sohonten name is retained from this knife's recorded identification. Its deba form is associated with traditional Japanese fish preparation, offering a broad blade for controlled cutting when breaking down fish. It is not intended for hard bones or frozen food. The wooden cover provides edge protection when correctly fitted. This individual blade's production date, exact steel grade and construction have not been established, so no specific era or forging method is claimed.

Care & Maintenance

• Dry immediately after use, including around the handle
• Avoid honing rods until the edge geometry is confirmed
• Sharpen on suitable water stones following the existing bevel; consult a specialist for unfamiliar single-bevel geometry
• Store fully clean and dry with the wooden cover only after confirming its fit
