What Is a Japanese Chef Knife (Gyuto)?

The Gyuto, often referred to as the Japanese Chef's Knife, is the Japanese interpretation of the classic Western chef knife. Originally developed for slicing meat, it has evolved into one of the most versatile kitchen knives available and is now considered an essential tool by professional chefs worldwide.

The KAI MGC-0406 is designed to handle virtually every cutting task in the kitchen, including:

• Slicing meat.

• Preparing large ingredients with precision.

If you want one premium knife capable of handling nearly every kitchen task, a Gyuto is the ideal choice.

Advanced Composite Blade Technology

The Seki Magoroku Composite collection showcases one of KAI's most innovative blade constructions.

Instead of using a single steel throughout the blade, KAI permanently joins two premium stainless steels using an advanced copper brazing process. This technology creates an exceptionally balanced blade while producing the distinctive copper line that has become the hallmark of the Composite series.

The cutting edge features a VG-MAX stainless steel core, hardened to approximately 61 ±1 HRC, providing:

• Outstanding edge retention.

• Exceptional cutting precision.

• Excellent wear resistance.

• Superior corrosion resistance.

• Reduced sharpening frequency.

• Long-term professional performance.

The upper section of the blade is made from SUS420J2 stainless steel, improving flexibility and impact resistance without sacrificing balance or cutting efficiency.

VG-MAX Steel – Premium Cutting Performance

VG-MAX is one of KAI's highest-performing stainless steels, developed specifically for premium Japanese kitchen knives.

Its advanced composition provides:

• Extremely sharp cutting edges.

• Long-lasting edge retention.
