1.Goodklife make steel by itself. Firstly we make steel through medium frequency furnace and then during ESR (electro slag remelting ), then will guarantee the raw material much purer.
2.Each blade will be forged, Goodklife never produce blades from steel sheet. After forging, the inside microstructure becomes much closer and the metal grain size becomes much smaller. It can elevate the characteristics and quality of the knife ensuring a longer life.
3.Each blade will be fully hardened. Fully harden means the surface hardness is exactly same as core hardness. Thus, the blades can be used after repairing until the size reached  design dimension.
4.All manufacturing processes are carried out in our plant, including steel-making, forging and heat treatment.This characteristic of Goodklife, allowed us to build a rich experience in the selection and process of tool steels.
5.We offer technical support regarding the selection of the most suitable steel grade and heat treatment, for all metal cutting application.
