  12. Cross Filing Cross filing involves holding the file at almost 90˚ to the work piece and filing across. This is the most basic filing technique and great care must be taken to keep the file as level as possible.

  13. Draw Filing Draw Filing produces a finer finish. Hold the file at right angles to the work and carefully move the file back and forth along the edge of the material

  14. File Card When filing any metal a file has a tendency to clog up. This is called Pinning. To avoid this you can rub chalk on the file before you use it. This fills up the pores and reduces pinning Occasionally you have to use a file card to clean the file. This is accomplished by rubbing the brush along the line of the teeth as shown above.

  15. File Storage Never store files in a tray. Rubbing the blades together like this will only cause the teeth to break.
