SG2 (Super Gold 2)
SG2 (Super Gold 2) steel is a premium Japanese powder steel often used for the production of high-end kitchen knives. This steel is known for its extreme hardness, excellent corrosion resistance and long lasting sharpness.
Features of SG2 steel in knives:
- High hardness (60-64 HRC) - thanks to powder metallurgy, it achieves higher strength than conventional carbon steels.
- Exceptional sharpness - can be sharpened to a very fine edge that will stay sharp for a long time even with heavy use.
- Corrosion resistance - the high chromium content (around 15-16%) provides protection against rust.
- Toughness - despite its hardness, SG2 is less brittle than other steels of similar hardness, reducing the risk of chipping.
- Microstructure - thanks to its fine-grained structure, it ensures a smooth cut and precise control of the knife.
SG2 steel manufacturers
SG2 is produced by the Japanese company Takefu Special Steel Co., Ltd., which is one of the leading manufacturers of special steels for the cutlery industry. The steel is produced by powder metallurgy, which ensures its high homogeneity and better mechanical properties compared to conventional stainless steels.
Knives made of SG2 steel
SG2 steel is used by renowned manufacturers of kitchen knives, especially from Japan. The most famous brands include:
- Suncraft - the Senzo Professional and Elegancia series use SG2 core coated with damascus steel.
- Miyabi (Zwilling Japan) - luxury knives with multi-layered damascus design and extreme sharpness.
- Shun (Kai Corporation) - high quality kitchen knives with SG2 core and damascus construction.

Why choose an SG2 steel knife?
SG2 steel knives are ideal for professional chefs and enthusiasts looking for top quality and long blade life. They're great for precision slicing of ingredients, whether it's meat, vegetables or fish.
Due to its properties, the SG2 is often used in high-end Japanese knives, where it is often combined with multi-layered damascus blades to enhance both aesthetic and functional value.
Summary: If you are looking for a premium knife that offers high hardness, long sharpness and corrosion resistance, the SG2 is a great choice. However, it does have one drawback - it's more expensive than regular steel, which matches its superior quality.
