Japanese Kitchen Knives | Shop by Steel

The steel a knife is forged from determines its edge retention, hardness, toughness and ease of sharpening. Popular Japanese knife steels include Aogami Super (Blue Super) for exceptional edge retention, Shirogami #1 and #2 (White Steel) for easy sharpening, SG2/R2 powdered stainless for low-maintenance performance, and VG10 for corrosion resistance. Use our filters to compare steel types and find the right balance for your kitchen. Knives and Stones provides expert guidance on every steel we carry.

常見問題

What is the difference between carbon and stainless Japanese knife steel?

Carbon steels (e.g. Aogami, Shirogami) take a sharper edge, are easier to sharpen on whetstones and offer superior edge retention, but they can rust and discolour without proper care. Stainless steels (e.g. SG2, VG10, AUS-10) resist corrosion and are lower maintenance, though generally harder to sharpen.

What is Aogami Super steel?

Aogami Super (Blue Super Steel) is a high-carbon steel made by Hitachi Metals. It contains added tungsten and vanadium for exceptional edge retention and wear resistance, typically hardened to 63–66 HRC. It is one of the highest-performing carbon steels available for kitchen knives.

What is SG2 / R2 steel?

SG2 (also marketed as R2) is a powdered metallurgy stainless steel made by Takefu Special Steel. It offers excellent edge retention at 62–64 HRC with strong corrosion resistance, making it a popular choice for high-performance stainless Japanese knives.

Which steel should a beginner choose?

For beginners, VG10 or Ginsan (Silver #3) stainless steels offer a forgiving balance of sharpness, corrosion resistance and ease of sharpening. If you are comfortable with knife care, Shirogami #2 carbon steel is an excellent entry point for traditional Japanese performance.
