gouge

A gouge is a deep, narrow cut or groove made intentionally or accidentally on a surface. It often occurs on wood, metal, or other materials and can result from tools, accidents, or wear over time. Gouges can weaken the material and may require repairs or refinishing. In woodworking, a gouge is also a specific tool used to carve out or shape wood, characterized by its curved blade designed for hollowing or detailed shaping. The term generally refers to a significant indentation or cut that alters the surface's smoothness and appearance.
