Whetted

Whetted refers to the state of an edge, typically that of a blade, having been sharpened. This process involves abrasion to create a thin, keen edge capable of cutting. The term can also be used metaphorically to describe an increased appetite or desire for something, as in "his appetite was whetted by the smell of food." This metaphorical usage implies that something has stimulated or sharpened a longing or interest. The opposite of whetted would be dull or blunt. Historically, whetting was a crucial skill for blacksmiths, cooks, and soldiers, as the effectiveness of tools and weapons depended on their sharpness. Modern sharpening techniques range from simple sharpening stones to electric grinders and professional sharpening services. The act of whetting implies a continuous or repeated process to maintain a desired level of sharpness.
