crowbar

This tool is defined by its function as a lever, utilizing mechanical advantage to exert significant force on stubborn objects. It carries a connotation of raw power and manual labor, often associated with demolition, construction, or forced entry. While similar to a pry bar, a crowbar is typically heavier and made of forged steel to withstand extreme pressure without bending.

In a figurative sense, the term is occasionally used to describe a tool or a piece of information that forces open a previously closed or stagnant situation. It suggests a sudden, forceful breakthrough rather than a gradual transition.
