Japanese Deba 180mm Masamoto 正本 kitchen knife

This is a premium **Japanese Deba knife** (180mm blade length) from the legendary **Masamoto Sohonten** (正本) brand, one of Japan's most respected and historic knife makers with over 150 years of craftsmanship, widely regarded as the top choice among professional sushi and fish chefs.


The Deba is a heavy-duty, single-bevel traditional knife designed specifically for breaking down whole fish—beheading, filleting, and cutting through small bones and cartilage with precision and power—while also suitable for poultry.


This example weighs a substantial 240g, providing excellent heft for controlled cuts. It features a classic wa-handle with a water buffalo horn ferrule.


The blade shows some light scratches and minor rust spots typical of carbon steel use, but the knife is in good overall condition and ready for immediate use in fish preparation. The buffalo horn ferrule has an extremely tiny chip that is barely noticeable and does not affect appearance or performance in any way.
