Japanese Blade Steel- SUS 405/ Ginsan 3 (Silver) laminate steel by Proterial. This is authentic Japanese blade steel imported directly from the maker by Vonhelmick Knife Co LLC. This is a high-performance laminated (clad) stainless steel primarily used in Japanese cutlery. It combines a hard, high-carbon stainless steel core for the cutting edge with a softer, ductile stainless steel cladding for protection and durability.
Core Steel: Ginsan 3 (Silver #3)
Developed by Proterial (formerly Hitachi Metals), this "Silver Paper" series steel is designed to mimic the performance of traditional carbon steels like Shirogami (White Steel) while being fully stainless.
Composition: Contains 0.95–1.10% Carbon and 13.0–14.5% Chromium.
Hardness: Typically heat-treated to 59–62 HRC.
Performance: Known for its fine grain structure, it offers edge sharpness and retention comparable to high-carbon steels but is easier to maintain and sharpen than more complex alloys like VG10.
Cladding Steel: SUS 405
In a laminate (San Mai) construction, SUS 405 serves as the outer "jigane" or cladding.
Properties: A 12% chromium ferritic stainless steel that is soft, ductile, and highly corrosion-resistant.
Function: It protects the Ginsan 3 core from snapping and makes the overall blade easier to thin or finish, as the outer layers are much softer than the hardened core.
Dimensions:
56.125 inches long,
1 inch wide,
6mm thick
weighs 58.5 ounces, which is 3.65 pounds.
