The method is often used in bladesmithing, for making knives and swords, to provide a very hard edge while softening the spine or center of the blade.This increased the toughness while maintaining a very hard, sharp, impact-resistant edge, helping to prevent breakage. The rate at which the metal is cooled depends on the metal and the properties desired. At this point the steel is no longer magnetic, and its color is cherry-red. or would like to After a metal has been soaked, it must be returned to room temperature to complete the heat-treating process.
