{"type":"firestarter.listing","listing":{"id":"lst_wKSPkk8v","product_name":"Yu Kurosaki Senko Ei SG2 Petty 130mm","category":"Petty Knife","description":"Overview\nThe Yu Kurosaki Senko Ei SG2 Petty 130mm is a compact utility knife built for precision tasks on and off the board—think trimming silverskin, segmenting citrus, hulling strawberries, or quick veg prep. “Senko” means “flash,” and the blade’s star-like hammered tsuchime scatters light while helping food release. The Ei profile adds a slightly more pointed tip for extra accuracy without sacrificing control.\nAt its core is powdered metallurgy SG2 (R2) stainless, heat-treated to about 62–63 HRC for excellent edge retention and crisp bite. Stainless cladding keeps day-to-day care simple: wash, dry, and stow. A thin 50/50 grind, light weight, and octagonal wa handle make it an easy, agile daily driver for home cooks and pros alike.\nCommon Questions\nQ: What’s the advantage of the “Ei” version?\nA: The Ei geometry is a touch more pointed at the tip, giving finer control for detail cuts (scoring, trimming herbs, citrus supremes) while keeping a familiar petty feel for general prep.\nQ: Is SG2 stainless hard to maintain?\nA: Not at all. It’s stainless core and cladding—just hand-wash, dry well, and use a wood or quality plastic board. Avoid bones, pits, or frozen foods to protect the fine edge.\nQ: How does a 130mm petty fit into a kit?\nA: It bridges paring and chef’s knives: small enough for in-hand work, long enough for quick board tasks. Many cooks keep it on the line for speedy, precise jobs.\nSpecifications\n\n\nCore Steel: SG2 (R2) Powder Stainless\n\nCladding Type: Stainless Steel\n\nBlade Length: 130mm\n\nOverall Length: 260mm (approx.)\n\nSpine Thickness (Heel): 2.1mm\n\nSpine Thickness (Mid): 1.9mm\n\nWeight: 67g\n\nHandle Material: Rosewood Octagonal (Wa) with Blonde Pakkawood Ferrule\n\nHardness (HRC): 62–63\n\nGrind: Double-bevel, 50/50\n\nFinish: Senko hammered tsuchime, polished\n","images":["https://cdn.shopify.com/s/files/1/0602/6720/0736/files/BA2C3D7B-6BA8-4B43-9E71-14C6F5838514.jpg?v=1730996886","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/C75B6B39-3C87-4B91-B504-42B9244145D2.jpg?v=1730996889","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/2D913025-F21D-4D97-928B-CBEB84C7E0A9.jpg?v=1730996894","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/02B8783F-0933-4492-9F8B-3F9654CD5AD4.jpg?v=1730996891"],"price":229,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:32.175Z"},"share_url":"https://firestarter.network/l/lst_wKSPkk8v","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
