{"type":"firestarter.listing","listing":{"id":"lst_2P3wUMhL","product_name":"Masamoto SW Swedish Steel Gyuto 240mm","category":"Kiritsuke Knife","description":"Overview\nThe Masamoto SW Swedish Steel Gyuto 240mm (model SW3124) is a classic wa-gyuto from Tokyo’s storied Masamoto Sohonten. Forged from Masamoto’s proprietary Swedish stainless (monosteel) and finished in a sleek migaki polish, it delivers the crisp, laser-like performance Masamoto is known for—without the day-to-day reactivity of carbon steel. Expect a thin, 2.9 mm spine at the heel tapering quickly, a tall ~50 mm blade for great knuckle clearance, and a light, agile feel around ~160–167 g. The traditional D-shaped magnolia handle with water-buffalo horn ferrule keeps the balance point right where you want it for all-day prep.\nMasamoto’s SW series targets pros and serious home cooks who love the famed KS profile but want the convenience of stainless. Heat-treated to ~HRC 58–60, it sharpens easily, holds a fine edge, and shrugs off humidity on the line—perfect for push, pull, and rocking cuts on proteins and produce alike.\nCommon Questions\nQ: Is this knife suitable for home cooks?\nA: Absolutely. The SW’s stainless construction means less fuss about rust, while the thin grind and tall profile make everyday slicing, dicing, and trimming feel effortless. If you’re upgrading from a Western chef’s knife, this is a superb first “serious” Japanese gyuto.\nQ: How does the SW compare to the Masamoto KS (White #2)?\nA: Think “same silhouette, different steel.” The KS uses reactive Shirogami #2 and is prized for its ultra-fine edge feel; the SW uses stainless for lower maintenance with similar KS-style geometry. If you want carbon-steel romance, go KS; if you want stainless convenience, go SW.\nQ: How should I care for it?\nA: Hand-wash, dry immediately, and store safely. Use a soft, knife-friendly board like the Hasegawa Pro. Lightly oil the blade during long storage with Tsubaki (camellia) oil. Touch up the edge on a strop—our Tokushu XL Buffalo Leather Strop is perfect—and when you want a pro edge, use our Sharpening Service.\nQ: How tall and how thin is the blade?\nA: Typica","images":["https://cdn.shopify.com/s/files/1/0602/6720/0736/files/masamoto-sw-swedish-steel-gyuto-240mm-01_ba09a779-ad7d-42c2-995e-010c6579089b.jpg?v=1780751927","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/masamoto-sw-swedish-steel-gyuto-240mm-02_5ef2843f-20c8-400d-a9bf-b67688ea9ac7.jpg?v=1780751927","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/masamoto-sw-swedish-steel-gyuto-240mm-03_72a42c8e-0d98-4beb-931a-4d92cc1aa285.jpg?v=1780751927","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/masamoto-sw-swedish-steel-gyuto-240mm-04_1d66c371-d19a-495c-9788-4952df8746e4.jpg?v=1780751927"],"price":499,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:30.412Z"},"share_url":"https://firestarter.network/l/lst_2P3wUMhL","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
