A cold chisel is a tool that can cut through "cold, " i.e. unheated, metal. This is in comparison to other blacksmith tools that are typically used only after the metal has been heated. Sometimes these chisels are also called "coal chisels".

Answer D is right because strong components are formed by forging.

A cold chisel is a tool made of tempered steel used for cutting 'cold' metals, meaning that they are not used in conjunction with heating torches, forges, etc.
