  1. Start with the BLACK handle file 65 HRC and run the file over the test material. If it marks the material, the material is less than 65 HRC.
  2. Try the BLUE handle file 60 HRC). If it does not mark the material, the file is softer than the material. In this case the material is between 60 and 65 HRC.
