Masamoto SW Swedish Steel Gyuto 240mm

Overview

The 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.

Masamoto’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.

Common Questions

Q: Is this knife suitable for home cooks?

A: 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.

Q: How does the SW compare to the Masamoto KS (White #2)?

A: 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.

Q: How should I care for it?

A: 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.

Q: How tall and how thin is the blade?

A: Typical measurements put heel height around ~50 mm with a spine ~2.9 mm at the heel, ~2.5 mm mid, and ~0.9 mm near the tip—thin, fast, and precise.
