{"type":"firestarter.listing","listing":{"id":"lst_inno5Rik","product_name":"Hatsukokoro Hayabusa VG-10 Tsuchime Bread Knife 210mm","category":"Bread Knife","description":"Overview\nThe Hatsukokoro Hayabusa VG-10 Tsuchime Bread Knife 210mm is a Japanese serrated bread knife designed for clean, controlled slicing through crusty sourdough, sandwich loaves, baguettes, pastries, tomatoes, and other foods with firm exteriors and soft interiors. The VG-10 stainless steel core gives this knife practical edge retention, good corrosion resistance, and easy care, making it a strong choice for both home cooks and professional kitchens.\nThe hammered tsuchime finish adds texture and visual character to the blade while helping distinguish it from ordinary bread knives. This version is finished with a burnt wood wa handle and black buffalo horn ferrule, giving it a warm, traditional Japanese look with a lightweight, comfortable feel in hand. At 210mm, it has enough length for most bread and pastry work without feeling oversized or awkward on the cutting board.\nUse this knife with a gentle sawing motion and let the serrated edge do the work. It is ideal for bread, tomatoes, cakes, sandwiches, and delicate baked goods, but it should not be used on bones, frozen food, or hard squash. Hand wash and dry immediately after use, and pair it with a knife-friendly board such as a Hasegawa Pro Cutting Board to help preserve edge performance.\nCommon Questions\nQ: Is the Hatsukokoro Hayabusa VG-10 Bread Knife good for home cooks?\nA: Yes. This is an excellent Japanese bread knife for home cooks who want cleaner slices, less tearing, and a stainless steel blade that is easy to maintain. VG-10 is a practical choice because it offers strong sharpness and edge retention without the extra care demands of reactive carbon steel.\nQ: What makes this different from a regular bread knife?\nA: The Hatsukokoro Hayabusa uses VG-10 stainless steel, a Japanese wa handle, and a refined tsuchime blade finish, giving it a lighter and more premium feel than many standard Western bread knives. The 210mm serrated blade is long enough for most loaves while still feeling nimble for pastrie","images":["https://cdn.shopify.com/s/files/1/0602/6720/0736/files/hatsukokoro-vg10-tsuchime-serrated-bread-knife-230mm-04_78844791-f57d-49a0-a978-8b04d7e7a6f1.jpg?v=1780759465","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/hatsukokoro-vg10-tsuchime-serrated-bread-knife-230mm-02_7e4a7b4c-277c-4d32-9834-20d968fdd707.jpg?v=1780759465","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/hatsukokoro-vg10-tsuchime-serrated-bread-knife-230mm-05_7b62d66d-2170-41e0-9019-974d6dac7310.jpg?v=1780759466","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/hatsukokoro-vg10-tsuchime-serrated-bread-knife-230mm-01_025bbe9f-6397-4f75-be61-720536161ab5.jpg?v=1780759465","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/hatsukokoro-vg10-tsuchime-serrated-bread-knife-230mm-03_e930d0db-83a0-4a41-baa2-e4671c120d15.jpg?v=1780759465"],"price":135,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:30.200Z"},"share_url":"https://firestarter.network/l/lst_inno5Rik","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
