Definition of the word hammer blow

The origin of the phrase "hammer blow" can be traced back to the late 1800s, when it was first used to describe the forceful impact of a hammer on a solid object. The word "hammer," of course, refers to the carpentry tool typically used for striking nails into wood, bricks, or other materials. The verb "to blow" in this instance has taken on a metaphorical meaning to indicate an intense, forceful, and sudden impact or force, much like the way a powerful wind or blast would move through an area. When the two words are combined, "hammer blow" implies a powerful, forceful, and sudden impact such as that produced by using a hammer as a tool, often with a loud and resounding noise that can be heard for some distance. Today, it is commonly used in contexts that require the description of a strong and forceful impact, such as in sports, engineering, and construction.
