Tsunehisa Ginsan Nawame Santoku // Nawame Damascus Japanese Knife // 165mm
The Santoku knife, meaning “three virtues,” is a versatile Japanese kitchen knife designed for slicing, dicing, and chopping meat, vegetables, and fish with ease. Its broad, short blade provides precision and efficiency, making it ideal for a wide range of cutting tasks in both professional and home kitchens.
The Ginsan Nawame series exemplifies premium Japanese kitchen knife craftsmanship, featuring a san mai construction with a Ginsan (Silver #3) stainless steel core and durable stainless cladding. Renowned for its fine grain structure, easy sharpening, and excellent corrosion resistance, Ginsan steel delivers clean, precise cuts and dependable edge performance, making it ideal for both professional chefs and home cooks.
A defining feature of the series is its distinctive blade finish. The cladding transitions from a highly polished, tight-band Damascus pattern into a bold Nawame texture near the spine—an industrial, rope- or rebar-inspired stamping that adds depth, grip, and dramatic visual contrast. This unique combination of refinement and rugged detail gives each knife a truly standout appearance.
Designed for comfort and cutting efficiency, the blade features a smoothly rounded choil for a comfortable pinch grip and a gentle convex grind that tapers to a thin, sharp edge. This geometry promotes effortless cutting, excellent food release, and precise control across a wide range of kitchen tasks.
Completed with an octagonal ebony handle and buffalo horn ferrule, the knife offers outstanding balance, stability, and a secure, natural feel in hand. Blending striking aesthetics with reliable performance, the Ginsan Nawame series delivers a high-end Japanese knife experience that performs as beautifully as it looks.

Ginsan steel, also known as Ginsanko, G3, or Silver #3, is a high-quality stainless steel developed by Hitachi Metals. It is valued for its ability to provide the sharpness and edge retention of traditional high-carbon steels while offering the corrosion resistance of stainless steel.
Composition of Ginsan (G3) Steel:
-
Carbon (C): ~0.95% - 1.05% (Increases hardness and edge retention)
-
Chromium (Cr): ~13.00% - 14.50% (Enhances wear resistance and toughness)
-
Manganese (Mn): ~0.60% - 1.00% (Aids in hardness and grain structure)
-
Silicon (Si): ~0.35% (Enhances strength and durability)
-
Phosphorus (P): ≤ 0.03% (Kept low to prevent brittleness)
-
Sulfur (S): ≤ 0.02% (Minimizes impurities for better toughness)
G3 Steel Characteristics:
-
Hardness: Can reach HRC 60-63 when properly heat-treated.
-
Corrosion Resistance: Due to its chromium content, it is stainless and resistant to rust.
-
Sharpness & Edge Retention: Performs similarly to traditional high-carbon steels like White #2 but with better stain resistance.
-
Ease of Sharpening: Relatively easy to sharpen compared to other stainless steels.
Ginsan is a popular choice for high-end Japanese knives because it provides an excellent balance of performance, ease of maintenance, and traditional high-carbon steel feel with the benefits of stainless steel.
