The 9F-10 saw sharpener is available to help you maintain the sharp edge on the blades of your ARS
saw during intensive use. The diamond profile of the file allows the user to get between the teeth on the saw and file them sharp. As with all professional tools the blades will get blunt/dull after intensive use and they should then be replaced with an original ARS blade. This will ensure your ARS saws give you many years of excellent use.
