Quick Summary

A chisel plow is a type of primary tillage equipment used to break and loosen soil. It features narrow, double-ended shovels, or chisel points, mounted on long shanks. These points penetrate the soil, stirring it without inverting or pulverizing it as much as moldboard or disk plows. Chisel plows are often used to loosen hard, dry soils before regular plowing or to break up compacted layers known as plow sole.123

A chisel, in a broader sense, is a cutting tool with a sharpened edge used for shaping materials like wood, stone, or metal. The term can also be used figuratively to describe obtaining something through shrewd or unfair practices.45
