What is the correct way to apply pressure when using a file?

Applying pressure on the forward stroke when using a file is the correct technique. This method is essential for several reasons. First, it allows for efficient material removal as the cutting edges of the file are designed to perform optimally when pushed forward. The action of pulling the file back, or on the return stroke, is generally a lighter motion that does not contribute to cutting but rather sets the file up for the next forward stroke.

In addition, applying pressure during the forward motion helps maintain control and direction, ensuring that the filing process remains effective and accurate. This technique minimizes the risk of damaging the workpiece or the file and enhances the clip and control over the filing operation. Using this method helps create smoother finishes on the surfaces being worked on, leading to a better overall result in the task at hand.
