The knife you find here is from Xin Cutlery, manufactured in Guandong, China. The 304Cu knife is a clad with two types of steels The first is a powdered tool steel and the other is 304Cu steel. The 304Cu steel is mainly 304 stainless steel including 4%-5% of copper added. The powder alloy mainly contains Ca-0.4%, Cr-16%, Ni-0.5%, Co-0.1%.
The two sheets of steel are clad together under the high heat of 1700℃. This technology is called plasma electrofusion and it was developed exclusively by this factory. The result is a high-hardness cutting edge with some antibacterial properties due to the copper added to the steel.
During our home-use tests the knife cuts well, holds an edge well, and the handle is top quality. It has an innovative twist design which feels good in the hand and looks great.
