moldboard

This term is highly specialized and primarily used within agricultural engineering and farming contexts. It describes a specific component of a moldboard plow, distinguishing it from other types of plows, such as chisel or disc plows, which do not invert the soil in the same manner.

Because it refers to a physical piece of machinery, it is used in a literal sense. It is rarely used metaphorically, and its usage is typically restricted to technical manuals, farming discussions, or historical accounts of agriculture.
