Nashiji Gyuto Chef Knife: Iron-Clad Steel & 62 HRC
Product Description
Xu Cheng Ji Hand-Forged Gyuto: The Pinnacle of Traditional Iron-Clad Craftsmanship
Technical Overview**
The Xu Cheng Ji (徐城记) Professional Gyuto represents a masterclass in traditional metallurgy, blending ancient techniques with high-performance modern standards. As a certified piece of Intangible Cultural Heritage (非遗厨刀), this knife is crafted using the legendary "White Plow" (Bai Li Di) forging technique. Unlike standard blades, this method involves polishing away the black oxide scale while meticulously preserving the authentic forged texture, resulting in a blade that is as aesthetically striking as it is functionally superior. This hand-forged (手工锻造) masterpiece is designed for culinary professionals who demand an uncompromising edge and a soul-stirring cutting experience.
Key Features and Construction**
San Mai Iron-Clad Construction:** Utilizing the classic 铁夹钢 (iron-clad steel) technique, a high-carbon T12A core is laminated between layers of softer iron. This provides the perfect balance of extreme hardness at the edge and structural resilience throughout the blade body.
T12A High-Carbon Core:** The heart of the blade features T12A钢, a premium high-carbon steel with a 1.2% carbon content. This material is renowned for its ability to achieve a laser-like sharpness that outclasses conventional stainless alloys.
Signature "White Plow" Finish:** The unique surface treatment removes the raw oxidation of the forge while highlighting the hammer marks, ensuring the blade glides through proteins with minimal friction.
Intangible Cultural Heritage:** Every knife carries the legacy of Xu Cheng Ji, representing centuries of refined Chinese forging expertise.
Performance Specifications**
Hardness:** Rated at a consistent 62 HRC (62硬度), achieved through a rigorous full-blade water quenching process. This ensures exceptional edge retention for high-volume professional environments.
Edge Geometry:** Hand-sharpened to a fine angle, the blade offers a superior "cutting feel" (切割感) that is both smooth and precise.
Maintenance:** Despite its high hardness, the T12A core is designed to be "easy to resharpen" (易复磨), allowing chefs to maintain a peak edge with standard whetstones.
Professional Applications**
This versatile 牛刀 (Gyuto) serves as a primary 主厨刀 (Chef Knife) for a variety of demanding tasks. Its profile is optimized as a 切肉刀 (meat slicer), making it ideal for precision slicing of proteins, detailed vegetable prep, and the delicate requirements of 日式料理刀 (Japanese-style cuisine). Whether you are executing fine julienne cuts or portioning large primals, the balance and sharpness provide effortless control.
Maintenance and Care**
As a professional-grade high-carbon tool, this knife requires dedicated care to maintain its performance.
1. **Hand Wash Only:** Clean with mild soap and dry immediately after use to prevent oxidation.
2. **Oil Coating:** Apply a food-safe mineral oil if the knife will be stored for an extended period.
3. **Whetstone Sharpening:** To preserve the 62 HRC edge, use high-quality whetstones rather than honing steels.
Experience the heritage of Xu Cheng Ji—where traditional craftsmanship meets the pinnacle of professional culinary performance.

Frequently Asked Questions
How should I sharpen this knife when it begins to dull?
The iron-clad design is optimized for easy maintenance using a traditional whetstone. Because of the hand-forged T12A core, we recommend using a medium to fine-grit water stone to restore its professional-grade sharpness without damaging the blade's geometry.
Can I use this hand-forged knife to cut through bones or frozen food?
No, this Gyuto is a precision instrument designed specifically for slicing meat and vegetables. Due to the high hardness of the T12A steel, the edge is brittle and may chip if used on hard materials like bones, pits, or frozen items.
What does 'Iron-clad steel construction' mean for the knife's durability and maintenance?
This traditional San Mai construction sandwiches a hard steel core between softer iron layers, making the blade resilient and much easier to resharpen. However, because it uses high-carbon materials, the blade should be wiped dry after each use to prevent oxidation and maintain the hand-forged finish.
What are the benefits of the 62 HRC hardness rating in this Gyuto knife?
The 62 HRC hardness, achieved through T12A core steel, provides exceptional edge retention and a razor-sharp cutting performance. This allows the knife to maintain its precision for professional meat and vegetable preparation longer than standard kitchen knives.
