Tool No. 2 is primarily used for what purpose?

The tool referred to as Tool No. 2 is primarily designed for chipping or removing metal. Tools specifically made for this purpose often have sharp edges and are shaped to efficiently shave off thin layers of metal or to break it away entirely, making them essential in metalworking tasks. This function is critical in various applications, such as fabricating metal parts, repairing machinery, and performing detailed work where precision is necessary.

In contrast, cutting thin sheet metal requires tools designed to handle lighter materials and produce clean edges without the risk of bending or distorting the metal, which doesn't align with the primary function of Tool No. 2. Shaping wood is typically the domain of carpentry tools like chisels or planes, which wouldn't apply here since Tool No. 2 specializes in metal. Finally, splitting nuts generally involves the use of nut splitters or specific wrench types designed to grip and apply torque, rather than a tool focused on chipping or removing metal.

The focus on metalworking tasks clarifies Tool No. 2's primary role and showcases its specialized design for efficient material removal in metal fabrication scenarios.
