  • Super Steel Knives: The Ultimate Blend of Sharpness and Durability for Professionals

    The Super Steel (Honyaki) knife is a rust-resistant and long-lasting professional-grade Japanese kitchen knife. It combines the finest traditional craftsmanship with modern manufacturing processes, making it an ideal tool for any chef seeking top performance.

  • Developed by Shiroyama Knife Workshop, this exclusive semi-stainless steel is designed to be highly resistant to rust, requiring less maintenance for daily use. The knife undergoes advanced processes, including vacuum heat treatment and sub-zero processing, resulting in an exceptionally high hardness of HRC62±1. This ensures the blade sharpens easily, holds its edge for an extended period, and is resistant to wear, even after frequent sharpening.

  • The Technology Behind Super Steel:

  • Vacuum Heat Treatment:

    In a vacuum environment, the steel is heated and rapidly cooled to prevent oxidation, resulting in uniform hardness and strength. This process minimizes distortion and ensures the knife remains durable even after long-term use.

    Vacuum Heat Treatment 
  • Sub-Zero Processing:

    After heat treatment, the steel is cooled to sub-zero temperatures, further enhancing its hardness and dimensional stability. This step is essential for achieving the knife’s superior performance.

    Sub-Zero Processing 
  • By combining these two advanced processes, the Super Steel knife achieves unparalleled sharpness, durability, and stability. It maintains its edge through even the toughest cutting tasks, elevating your cooking experience.

  • If you're looking for a high-quality knife that will last for years, the Super Steel knife exceeds expectations with every cut.
