A steak knife is a sharp table knife, used for cutting steak. These often feature serrated blades and wooden handles, and are the only sharp knife commonly found at the modern table. Specialized steak knives emerged in America following World War II. Prior to World War I, all table knives were sharp, but required frequent upkeep – sharpening and polishing. With the decline in domestic workers (household servants), this upkeep became less feasible. Stainless steel became widespread following WWI, which did not require polishing, but did require sharpening due to manufacturing limits. Following WWII, serrated stainless steel steak knives were introduced which required neither polishing nor frequent sharpening, and proved an instant hit.
