Practical tips for best results
- Secure your workpiece and work in a well-lit area to monitor progress and avoid over-filing.
- Grip the file toward the back for better leverage, and apply steady, even pressure with long, consistent strokes toward the tip.
- Wipe away chips frequently and use a file card to keep teeth clean; light lubrication isn’t always necessary but can help with sticky metals.
