{"type":"firestarter.listing","listing":{"id":"lst_Hk5F5Fbn","product_name":"Masakage Shimo White #2 Damascus Petty 150 mm","category":"Petty Knife","description":"Overview\nHand-forged in Takefu Knife Village by rising star Yu Kurosaki, the Masakage Shimo Petty 150 mm packs katana-level bite into a nimble utility blade. A razor-hard White #2 core rides inside a dramatic, X-hammered Damascus cladding that evokes frost on glass, giving the line its name “Shimo” (霜). At just 74 g, it darts through herbs, citrus, and proteins while the octagonal magnolia handle offers sure grip for both board and in-hand work. Treat it well, and the edge will polish to screaming sharpness in minutes.\nCommon Questions\nQ: Is a 150 mm petty big enough for everyday prep?\nA: Absolutely. Think of it as a chef’s knife in “fun-size”—long enough for garlic, chicken trimming, and sandwich duty, yet precise enough to peel an apple.\nQ: How should I maintain White #2 carbon steel?\nA: Wash by hand, dry immediately, and oil occasionally. A quick wipe keeps patina classy instead of rusty, a stop will keep the edge tuned between sharpening sessions.\nSpecifications\n\n\nCore Steel: Hitachi White #2 carbon\n\nCladding Type: Reactive iron Damascus (X-hammer “frost” pattern)\n\nBlade Length: 150 mm (edge length 152 mm)\n\nOverall Length: 279 mm\n\nSpine Thickness (Heel): 3 mm\n\nSpine Thickness (Mid): Specs not found\n\nBlade Height: 29 mm\n\nWeight: 74 g\n\nHandle Material: Octagonal magnolia wood with black pakka ferrule\n\nHardness (HRC): ~61-63\n","images":["https://cdn.shopify.com/s/files/1/0602/6720/0736/files/masakage-shimo-white2-petty-150mm-01_0a7fa6fd-9f6f-4c3a-bfeb-d1ad7bacc97e.jpg?v=1780760727","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/masakage-shimo-white2-petty-150mm-02_2d791e56-d953-4405-9b82-40d697565406.jpg?v=1780760727","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/masakage-shimo-white2-petty-150mm-03_9c01606d-cbeb-45e3-bb97-6b3ac4d70bff.jpg?v=1780760727"],"price":245,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:30.554Z"},"share_url":"https://firestarter.network/l/lst_Hk5F5Fbn","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
