A screwdriver shall not be used as a punch or a ?.

Using a screwdriver as a chisel is not appropriate due to the design and intended function of each tool. A screwdriver is specifically crafted for turning screws and may not withstand lateral or impact forces, which are commonly applied when using a chisel. Attempting to use a screwdriver in this way can lead to tool damage and personal injury, as screwdrivers can easily break or snap under such conditions. Tools like chisels are designed with a specific cutting edge and robust structure to handle the necessary forces involved in cutting into materials. Each tool has its purpose, and using them outside of their intended applications compromises safety and effectiveness.
