Characteristics of Rooij Customs

For this limited edition of Rooij Customs knives, we imported separate blades and handles from Japan. We then carefully assembled them by hand. This is a precise process. First, we heat the tang of the blade to ensure a perfect fit inside the handle. Afterwards, we fill the handle with epoxy and heat the tang once more.

After we carefully center the blade, the handles are hermetically sealed with a piece of self-drying clay so that no water or dirt can enter and damage the wood. In this case, the blade has a AUS10 steel core and the handle is made of rosewood.

AUS-10 / 10A Steel (Aichi Steel)

AUS-10 is a stainless steel produced by the steel manufacturer Aichi Steel. Thanks to its high chromium content, the steel offers excellent corrosion resistance. It is widely regarded as a well-balanced all-round steel, combining sharpness, ease of maintenance, and durability.

Compared to VG-10, AUS-10 is slightly softer and therefore more forgiving in use. The hardness typically ranges from 59–61 HRC, depending on the maker and the heat-treatment process used. The addition of vanadium and molybdenum improves wear resistance, reduces chipping, and helps the blade retain its edge well.

An ideal steel for both enthusiastic home cooks and professional chefs.
