Heritage & Use

The existing marking notes transcribe the main stamp as 正本 (Masamoto) and the smaller stamp as 登録商標 (registered trademark). These recorded readings have not been independently authenticated, and the circular logo does not establish a specific production run here. No production date or golden-era provenance has been established, and earlier inspection and ready-to-use claims are not supported by documented assessments. The gyuto format offers options for general preparation, subject to checking the blade, edge and handle. Carbon steel can develop a natural patina with use and requires prompt drying.

Care & Maintenance

• Hand wash only; never use a dishwasher
• Dry immediately and avoid soaking the wood handle
• Hone only with a method appropriate to the existing edge geometry and condition
• Sharpen on suitable water stones preserving the existing bevel, or consult a specialist
• Apply a light coat of food-safe oil before extended storage
• Remove active rust rather than treating it as patina
• Store clean and dry with the edge protected
