{"type":"firestarter.listing","listing":{"id":"lst_WE3yC3yX","product_name":"Hatsukokoro Aokitae Blue #2 Kurouchi Santoku 180mm with Sanjo Walnut and Maple Stripe Handle","category":"Santoku Knife","description":"Overview\nThe Hatsukokoro Aokitae Blue #2 Kurouchi Santoku 180mm with Sanjo walnut and maple stripe handle is a rustic, all-carbon Japanese kitchen knife built for cooks who want strong cutting feel, easy sharpening, and the character that only reactive steel can develop over time. The Aokitae line is known for delivering excellent value in Blue #2 steel, pairing a kurouchi finish with soft iron cladding for a traditional look and lively feel on the board. In santoku form, this knife is especially useful for the three classic kitchen jobs it is named for: slicing, dicing, and mincing.\nBlue #2 is one of the most loved carbon steels in Japanese cutlery because it offers a sweet spot between edge retention, toughness, and sharpening ease. That means this santoku is well suited to home cooks moving into higher-end Japanese knives, but it also has the kind of crisp feedback and edge potential that enthusiasts appreciate. The Sanjo walnut handle with maple stripe gives the knife a warmer, more refined presentation while keeping the overall feel comfortable and nimble in hand.\nOn the board, expect clean performance on vegetables, herbs, boneless proteins, and everyday prep. The santoku profile makes it especially friendly for push cutting, chopping, and precise home kitchen work where a shorter blade can feel more agile than a full gyuto. Because this knife uses reactive carbon steel with reactive iron cladding, it should be washed and dried promptly after use. For longer storage, a light coat of tsubaki oil is a smart habit, and regular touch-ups on a leather strop can help keep the edge feeling fresh between sharpenings.\nCommon Questions\nQ: Is this santoku suitable for home cooks?\nA: Yes. This is a very good choice for a home cook who wants to step into true Japanese carbon steel. The santoku shape is approachable, versatile, and easy to control, while Blue #2 offers excellent sharpness without being overly difficult to maintain or sharpen.\nQ: What does kurouchi mean, and","images":["https://cdn.shopify.com/s/files/1/0602/6720/0736/files/hatsukokoro-aokitae-blue-2-kurouchi-santoku-180mm-2_43dbe3a5-45df-4e56-ba80-1e82f4612664.jpg?v=1780744538","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/hatsukokoro-aokitae-blue-2-kurouchi-santoku-180mm-6_30ead15c-2b4d-4b14-a768-099b53e68452.jpg?v=1780744538","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/hatsukokoro-aokitae-blue-2-kurouchi-santoku-180mm-3_d1d6d83c-76b0-4420-bb08-7cc944a9da03.jpg?v=1780744538","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/hatsukokoro-aokitae-blue-2-kurouchi-santoku-180mm-1_55fa9ac1-5e3c-43a1-b53b-4271a600f525.jpg?v=1780744538","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/hatsukokoro-aokitae-blue-2-kurouchi-santoku-180mm-4_ce4fcd32-1420-4193-b099-1ffd74c9bfdc.jpg?v=1780744538","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/hatsukokoro-aokitae-blue-2-kurouchi-santoku-180mm-5_1291f4cb-e959-4581-8b1c-6fdc44fe73c5.jpg?v=1780744538"],"price":135,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:30.293Z"},"share_url":"https://firestarter.network/l/lst_WE3yC3yX","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
