Only steel from selected and well-known steelworks can be used to produce LUK knives. And a quality assurance certificate for each batch of steel is a must.
After the steel arrives at LUK plant, we perform metallographic analysis and chemical composition test in our in-house laboratory equipped with advanced testing instruments. Third-party lab tests can also be carried out when it is necessary. All these are taken to ensure the quality of the material.
This strict standard is followed for all kinds of steel we use, such as high grade martensitic stainless steel, tool steel, high speed steel, powder metal steel, and ultra-fine particle tungsten carbide. And the application of new materials is always an important project of LUK engineering team.
