{"type":"firestarter.listing","listing":{"id":"lst_oIPoXD5_","product_name":"Imai AS Kurouchi USA Gyuto 220mm with Sanjo Walnut Handle","category":"Gyuto Knife","description":"Overview\nThe Imai AS Kurouchi USA Gyuto 220mm is a tall, powerful Japanese chef knife built for cooks who want carbon steel edge performance, excellent board presence, and a rustic forged look. With a 221mm blade length, 61.5mm heel height, and 177g weight, this gyuto offers excellent knuckle clearance, confident food contact, and a balanced feel for daily prep.\nAt the core is Aogami Super, also known as Blue Super steel, one of the most respected high-carbon steels used in Japanese kitchen knives. It is known for excellent edge retention, strong sharpening response, and the ability to take a very refined edge. The kurouchi finish gives the blade a traditional forged appearance while adding rustic character above the cutting edge.\nThis knife is paired with a Sanjo walnut octagonal handle with a maple stripe, giving it a comfortable, natural feel with a clean custom look. The 220mm size sits between a classic 210mm gyuto and a full 240mm workhorse, making it a strong all-around choice for cooks who want extra cutting room without stepping into an oversized blade.\nCommon Questions\nQ: Is the Imai AS Kurouchi Gyuto 220mm good for home cooks?\nA: Yes.

It is a carbon steel, so it should be washed and dried carefully after use.\nQ: How should I care for this kurouchi carbon steel knife?\nA: Do not leave it wet or dirty on the board.
