What is the origin of the idiom "cut and thrust" and when to use it?

The phrase "cut and thrust" originates from the world of sword fighting, particularly fencing, where "cut" refers to the motion of making a slashing or cutting movement with a sword, and "thrust" refers to the action of stabbing or pushing the sword forward in an attack. Over time, "cut and thrust" was adopted in a more figurative sense to describe vigorous and competitive exchanges, debates, or interactions where opposing viewpoints or actions are in play. It captures the idea of dynamic and spirited engagement, much like the rapid and decisive movements of a swordsman.
