Properties 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 intensive use.
- Corrosion resistance - high chromium content (about 15-16%) provides protection against rust.
- Toughness - despite its hardness, SG2 is less brittle than other steels of similar hardness, which reduces the risk of chipping the blade.
- Microstructure - thanks to its fine-grained structure, it ensures a smooth cut and precise control over 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.
SG2 steel knives
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 uses an SG2 core wrapped in Damascus steel.
- Miyabi (Zwilling Japan) – luxury knives with a multi-layered Damascus design and extreme sharpness.
- Shun (Kai Corporation) - high quality kitchen knives with SG2 core and damascus construction.

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