Is it acceptable to strike files with a hammer for added pressure?

Striking files with a hammer for added pressure is not an acceptable practice because it can damage the file and potentially lead to injury. Files are designed to cut or shape material through their tooth structure and are not intended to withstand impact from a hammer. Using a hammer can cause the teeth to chip or break, rendering the file ineffective. Additionally, it increases the risk of slipping or misalignment, which can lead to accidents and injuries. Proper filing techniques involve using the file with controlled hand pressure, allowing for a more precise and effective material removal without compromising the integrity of the tool.
