They can only be used to repair details. Use it as a file. At the same time, it can push the file along the direction of the blade to make a neat blade line.

In order to prolong the service life of files, the following rules must be observed:
1. Do not use new files to file hard metals. 2. It is not allowed to use files to frustrate hardened materials. 3. Forgings and castings with hard skin or sticky sand must be ground off on a grinder before they can be filed with a semi-sharp file. 4. Use one side of the new file first, and then use the other side when that side is blunt. 5. When filing, always use a wire brush to clean the swarf on the teeth. 6. Files must not overlap or be stacked with other tools. 7. When using a file, the speed should not be too fast, otherwise it is easy to wear prematurely. 8. The file should be protected from water, oil or other dirt. 9. Fine files are not allowed to file soft metals. 10. Do not use too much force with assorted files to avoid breaking
