{"type":"firestarter.listing","listing":{"id":"lst_1ba6Bs0o","product_name":"Masakage Koishi Stainless Clad Aogami Super Ko Bunka","category":"Bunka Knife","description":"The Masakage Koishi Ko-Bunka 130 mm packs full-sized performance into a palm-friendly blade. Forged by Echizen master Yoshimi Kato from ultra-hard Aogami Super, then hand-sharpened by Takayuki Shibata, it pairs a pebble-textured tsuchime hammer pattern with a protective kurouchi layer over stainless cladding. The result looks like river stones caught in midnight fog—yet cuts with laser-like ease. At 130 mm, the Ko-Bunka keeps knuckle clearance while feeling as nimble as a petty, making it a do-everything companion for quick veg prep, herb chiffonades, or on-the-fly protein trimming.\nCommon Questions\nQ: Is 130 mm long enough for daily meal prep?A: Absolutely. The tall profile and flat edge let you chop cucumbers, mince garlic, or portion chicken breasts without wanting more length. Only large roasts or melons may need a longer blade.\nQ: Does the Aogami Super core rust easily?A: The core is reactive, but the stainless cladding covers most of the blade. Wash, dry, and store promptly; a pleasant grey patina will form on the edge over time.\nQ: How often will I need to sharpen it?A: With its HRC 63–64 hardness, the edge lasts many weeks in home use. A quick touch-up on a 3 k stone or strop restores “shave-sharp” in minutes.\nSpecifications\n\n\nCore Steel: Aogami Super carbon steel\n\nCladding Type: Stainless, kurouchi tsuchime finish\n\nBlade Length: 130 mm\n\nOverall Length: 260 mm\n\nSpine Thickness (Heel): 2.2 mm\n\nSpine Thickness (Mid): 1.8 mm\n\nBlade Height: 31.9 mm\n\nWeight: 68 g\n\nHandle Material: Octagonal cherry wood with black pakkawood ferrule\n\nHardness (HRC): 63–64\n","images":["https://cdn.shopify.com/s/files/1/0602/6720/0736/files/masakage-koishi-as-ko-bunka-130mm-1_a8e8e9a1-c9ba-444e-8c2f-87e04e6fb32f.jpg?v=1780768355","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/masakage-koishi-as-ko-bunka-130mm-2_78845965-0b7c-4e44-bd16-c1608eb75855.jpg?v=1780768355","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/masakage-koishi-as-ko-bunka-130mm-3_d74696fe-c893-4bdf-ac90-b8671b27b942.jpg?v=1780768355"],"price":269,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:30.539Z"},"share_url":"https://firestarter.network/l/lst_1ba6Bs0o","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
