    Tips: Maintenance of files

    1. There are burrs on the teeth of the new file. If you use a new file to cut hard metals, the burrs will be worn off and the file will be blunt early. Therefore, you cannot file hard iron and steel with a new file.
    2. Do not use new files to polish the iron oxide or cast crust surface and unannealed hard steel parts. The iron oxide and cast crust must be ground off on the grinding wheel first. Only in unavoidable circumstances can the old file be used.
    3. Do not use the fine file to sharpen the soft metals (lead, tin, etc.), because the debris of soft metals is easy to be embedded in the grooves of the teeth, and the file will slip on the surface of the workpiece.
    4. Do not stack files together to avoid damage to the teeth.
    5. Do not make the file wet or place it in a damp place to prevent corrosion.
    6. When filing soft metal, the teeth of the file are often blocked by the debris. At this time, the debris layer can be brushed off with a brush. In order to avoid the teeth of the file being blunt by the brush, the wire brush should be brushed to the hooked side along the direction of the file teeth. If the large debris is embedded, it should be scraped off with a copper scraper, but it must be removed in the direction of the file tooth.
