Tosa Tsuboya Santoku 180mm Aogami No. 2 Kurouchi

Tosa Tsuboya Santoku 180mm – Aogami no.2 Kurouchi

Santoku from the forge of craftsmen in the Tosa region on the Japanese island of Shikoku – an area with a deep tradition of tool and knife making. The Kurouchi finish (raw blacksmith's skin) gives the blade an authentic, industrial character and naturally protects it from corrosion.

Specifications

• Blade: 180 mm
• Steel: Aogami no.2 (Blue Steel #2) – high-carbon tool steel with excellent sharpness and ability to take a very fine edge
• Blade finish: Kurouchi (raw blacksmith's skin)
• Handle: Walnut, approx. 130 mm long, Japanese style (wa-handle)
• Type: Santoku (all-purpose kitchen knife)

Blade Characteristics

Aogami no.2 is a popular steel among Japanese chefs and knife enthusiasts alike. It sharpens easily to a very fine edge and holds it for a long time. The Kurouchi finish minimizes food sticking and gives the knife a rustic aesthetic straight from the forge.

Maintenance Recommendations

• Hand wash, dry immediately – the steel is not stainless and can rust without care
• Lightly oil after use (camellia or neutral oil)
• Sharpen on Japanese water stones, recommended grit 1000–3000 for regular maintenance
• Store on a magnetic strip or in a wooden block

Warning

The knife is made from reactive high-carbon steel. When in contact with acidic foods (citrus, tomatoes), patination may occur – this is a natural process that does not affect functionality or safety. The knife is not dishwasher safe.
